List	Outcome	Time frame	Description
Primary	Number of Participants With Solicited Adverse Events (AEs) During Days 1-7	Days 1 through 7	Participants were evaluated for solicited adverse events while in the NICU/ICU on days 1-7. Participants were counted if they experienced the symptom at any severity during the reporting period. Although participants received only 5 days of mupirocin, solicited events were collected through day 7.
Primary	Number of Participants With Moderate and Severe Unsolicited Adverse Events; During Days 1-7	Days 1 through 7	Participants were evaluated for moderate and severe unsolicited adverse events (that were not otherwise considered pre-defined trial endpoints) while in the NICU/ICU on days 1-7. Although participants received 5 days of mupirocin, unsolicited events were collected until day 7. Moderate events were defined as those that may cause some interference with functioning and daily activities. Severe events were defined as those that interrupt the participant's usual daily activities and may require systemic drug therapy or other treatment. Severe events were usually incapacitating.
Primary	Number of Participants With Serious Adverse Events (SAEs) During Days 1-7	Days 1 through 7	Participants were evaluated for Serious Adverse Events (SAEs) while in the NICU/ICU on days 1-7. Although participants received only 5 days of mupirocin, SAEs were collected through day 7. An adverse event or suspected adverse reaction was considered serious if, in the view of either the investigator or sponsor, it resulted in any of the following outcomes: death; a life-threatening adverse event (an event that places the participant at immediate risk of death; it doesn't include an adverse event, had it occurred in a more severe form, might have caused death); inpatient hospitalization or prolongation of existing hospitalization; a persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions; or any other event that when based upon appropriate medical judgement may have jeopardized the participant and may have required medical or surgical intervention to prevent one of the outcomes listed in this definition.
Primary	Primary Decolonization Efficacy- Number of Participants in the Treatment and Control Groups Who Have no Detectable S. Aureus (SA) on Direct Nasal, Umbilical, and Perianal (NUP) Cultures Obtained on Day 8.	Day 8	Colonization was defined as the presence of SA identified by NUP culture without signs of illness or infection. On day 8, participants were swabbed in each of three areas: nasal, umbilical, and perianal. These swabs were cultured by direct plating. If SA did not grow on any of these cultures the infant was considered to be decolonized. If SA grew on any one of these cultures the infant was considered to be colonized with SA.
Primary	Persistent Decolonization Efficacy- Number of Participants in the Treatment and Control Groups Who Have no Detectable S. Aureus (SA) on Direct Nasal, Umbilical, and Perianal (NUP) Cultures on Days 8 and 22.	Day 8 and Day 22	Participants were admitted into the study based on being colonized with SA. Participants who were decolonized both on day 8 and day 22, as determined by NUP cultures were considered to have persistent decolonization. Colonization was defined as the presence of SA identified by NUP culture without signs of illness or infection. NUP swabs were collected on day 8 and on day 22 and cultured by direct plating. If the cultures were negative for SA at both day 8 and day 22 the participant was considered to have persistent decolonization. Colonization with SA was a prerequisite for enrollment, because of this there was no baseline measure.
Secondary	Relative Risk of Occurrence of Non-SA Clinical Infection in the Treatment Compared to Control Group in the Intent To Treat Cohort	Day 1 through 85	Relative risk of occurrence of non-SA clinical infection in the treatment compared to the control group using the intent to treat (ITT) cohort for analysis. The time periods in the table correspond to the study days having scheduled collection of nasal, umbilical, and perianal (NUP) cultures. At risk participants were eligible for the non-SA clinical infection to occur at the start of the interval, were still on study and had not yet had a non-SA clinical infection but were still being watched for the event. Non-SA clinical infection was the development of a non-SA clinical infection due to an identifiable organism as evidenced by culture of an organism other than SA from a normally sterile body site or an infant who met the clinical diagnosis of localized infection as defined in the protocol. Censored participants were at risk for some of the interval, did not have a non-SA clinical infection but were removed from eligibility for the event at some point after the interval started.
Secondary	Relative Risk of Occurrence of Non-SA Clinical Infection in the Treatment Compared to Control Group in the According to Protocol Cohort.	Day 1 through 85	Relative risk of occurrence of non-SA clinical infection in the treatment compared to control groups using the according to protocol (ATP) cohort. The time periods in the table correspond to the study days having scheduled collection of nasal, umbilical, and perianal (NUP) cultures. At risk participants were eligible for the non-SA clinical infection to occur at the start of the interval, were still on study and had not yet had a non-SA clinical infection but were still being watched for the event. Non-SA clinical infection was the development of a non-SA clinical infection due to an identifiable organism as evidenced by culture of an organism other than SA from a normally sterile body site or an infant who met the clinical diagnosis of localized infection as defined in the protocol. Censored participants were at risk for some of the interval, did not have a non-SA clinical infection but were removed from eligibility for the event at some point after the interval started.
Secondary	Median Time to Occurrence of Severe (Stage II-III) Necrotizing Enterocolitis (NEC) in the Treatment Compared to Control Group.	Day 1 through 85	Median time to occurrence of severe (stage II-III) NEC in the treatment compared to control group as estimated using Kaplan-Meier estimates of the survival curves.
Secondary	Protective Efficacy of Clinical S. Aureus (SA) Infection in the Treatment Compared to the Control Group During Days 1-22 or Until Discharge, Whichever Occurs First, Using the Intent to Treat Cohort.	Day 1 through 22	Protective efficacy of clinical SA infection in the treatment compared to the control group during days 1-22 or until discharge, whichever occurs first using the intent to treat (ITT) cohort. The time periods in the table correspond to the study days having scheduled collection of nasal, umbilical, and perianal (NUP) cultures. At risk participants were eligible for the SA clinical infection to occur at the start of the interval, were still on study and had not yet had a SA clinical infection but were still being watched for the event. SA clinical infection was the development of a SA clinical infection due to an identifiable organism as evidenced by culture of an organism from a normally sterile body site or an infant who met the clinical diagnosis of localized infection as defined in the protocol. Censored participants were at risk for some of the interval, did not have a SA clinical infection but were removed from eligibility for the event at some point after the interval started.

Secondary	Median Time to Occurrence of Non-S. Aureus (SA) Clinical Infection in the Treatment Compared to Control Group	Day 1 through 85	Median time to occurrence of non-SA clinical infection in the treatment compared to control group as estimated using Kaplan-Meier estimates of the survival curves.
Secondary	Relative Risk of Severe (Stage II-III) Necrotizing Enterocolitis (NEC) in the Treatment Compared to Control Group	Day 1 through 85	The association between mupirocin treatment and severe (stage II-III) NEC on or before Day 85 was to be assessed via Cox Proportional Hazards Model.
Secondary	Time Until Decolonization: Count of Participants From Day 1 Until the First NUP Collection With no S. Aureus (SA) Detected in the Nares, Umbilical, and Perianal Areas Using the Modified Intent to Treat Day 8 Cohort (mITT-8).	Day 1 through 85	Time until decolonization: Count of participants from Day 1 until the first NUP collection with no SA is detected in the nares, umbilical, and perianal areas using the modified intent to treat (mITT-8) cohort. The time periods in the table correspond to the study days having collection of nasal, umbilical, and perianal (NUP) cultures. At risk participants were eligible for the SA decolonization to occur at the start of the interval, were still on study and had not yet had SA decolonization but were still being watched for the event. SA decolonization was the absence of SA detected from the NUP cultures through direct plating. Censored participants were at risk for some of the interval, did not have SA decolonization but were removed from eligibility for the event at some point after the interval started.
Secondary	Time Until Decolonization: Count of Participants From Day 1 Until the First NUP Collection With no SA is Detected in the Nares, Umbilical, and Perianal Areas Using the According to Protocol Day 8 (ATP-8) Cohort.
