ListOutcomeTime frameDescription
PrimaryIncidence Rate for the First Pneumonia Event
From the index date (i.e. between 01 January 2005 and 30 April 2015) up to the earliest of discontinuation of the index drug (i.e. LAMA or ICS/LABA), death, or 30 April 2016 (i.e. cut-off date for data retrieving), up to 136 months.
Pneumonia was defined as ≥1 inpatient or outpatient claims 1) with ICD-10 codes for pneumonia recorded as any diagnosis in inpatient claims or primary \~ 4th secondary diagnosis in outpatient claims, AND 2) with diagnostic test code for chest-X ray or chest- computed tomography (CT), AND 3) with antibiotics prescription during the following period after the index date. To assess the incidence of pneumonia event, the first pneumonia event observed during the follow-up period was considered. Incidence rate for the first pneumonia event was calculated as below: Incidence rate per 1000 person-years= Number of patients with event/ sum of event-free period during the follow-up period (1000 person-years)
PrimaryIncidence Rate of Pneumonia Events
From the index date (i.e. between 01 January 2005 and 30 April 2015) up to the earliest of discontinuation of the index drug (i.e. LAMA or ICS/LABA), death, or 30 April 2016 (i.e. cut-off date for data retrieving), up to 136 months.
Pneumonia was defined as ≥1 inpatient or outpatient claims 1) with ICD-10 codes for pneumonia recorded as any diagnosis in inpatient claims or primary \~ 4th secondary diagnosis in outpatient claims, AND 2) with diagnostic test code for chest-X ray or chest- computed tomography (CT), AND 3) with antibiotics prescription during the following period after the index date. This outcome measure reports: Total number of pneumonia events/ sum of follow-up duration (person-years) for all participants
PrimaryTime to First Pneumonia Event From the Index Date
From the index date (i.e. between 01 January 2005 and 30 April 2015) up to the earliest of discontinuation of the index drug (i.e. LAMA or ICS/LABA), death, or 30 April 2016 (i.e. cut-off date for data retrieving), up to 136 months.
Pneumonia was defined as ≥1 inpatient or outpatient claims 1) with ICD-10 codes for pneumonia recorded as any diagnosis in inpatient claims or primary \~ 4th secondary diagnosis in outpatient claims, AND 2) with diagnostic test code for chest-X ray or chest- computed tomography (CT), AND 3) with antibiotics prescription during the following period after the index date. Date of pneumonia event was defined as the starting date of outpatient claim, or as the admission date of inpatient claim with the above 3 conditions to define pneumonia event. Mean and Standard Deviation of time to first pneumonia event from the index date was estimated using the Kaplan-Meier curve.

Pneumonia was defined as ≥1 inpatient or outpatient claims 1) with ICD-10 codes for pneumonia recorded as any diagnosis in inpatient claims or primary \~ 4th secondary diagnosis in outpatient claims, AND 2) with diagnostic test code for chest-X ray or chest- computed tomography (CT), AND 3) with antibiotics prescription during the following period after the index date. Number of patients with pneumonia event is reported.
PrimaryIncidence Rate of the First Chronic Obstructive Pulmonary Disease (COPD) Exacerbation Event (All Types)Up to 12 months from the index date. Index date was between 01 January 2005 and 30 April 2015.
To assess the incidence of COPD exacerbation event (all types), the first COPD exacerbation event among pre-defined moderate COPD exacerbation and severe COPD exacerbation event observed within the 12-month period after the index date was considered. Moderate COPD exacerbation was defined as ≥ 1 outpatient claims 1) with ICD-10 codes for COPD recorded as primary \~ 4th secondary diagnosis, AND 2) with systemic steroids and/or antibiotics prescription within 12 months after the index date. Severe COPD exacerbation was defined as ≥ 1 Emergency Room (ER) visit or inpatient claims 1) with ICD-10 codes for COPD or diseases due to COPD worsening as any diagnosis, AND 2) with systemic steroids and/or antibiotics prescription. Incidence rate of COPD exacerbation events (all types) was calculated as below: Incidence rate per 1000 person-years= Number of patients with event/sum of event-free period during the follow-up period (1000 person-years)
PrimaryIncidence Rate of Chronic Obstructive Pulmonary Disease (COPD) Exacerbation Events (All Types)Up to 12 months from the index date. Index date was between 01 January 2005 and 30 April 2015.
To assess the frequency of all types (moderate and severe) COPD exacerbation events, any events observed within the 12-month period after the index date was considered. Moderate COPD exacerbation was defined as ≥ 1 outpatient claims 1) with ICD-10 codes for COPD recorded as primary \~ 4th secondary diagnosis, AND 2) with systemic steroids and/or antibiotics prescription within 12 months after the index date. Severe COPD exacerbation was defined as ≥ 1 Emergency Room (ER) visit or inpatient claims 1) with ICD-10 codes for COPD or diseases due to COPD worsening as any diagnosis, AND 2) with systemic steroids and/or antibiotics prescription.

Severe COPD exacerbation was defined as ≥ 1 Emergency Room (ER) visit or inpatient claims 1) with ICD-10 codes for COPD or diseases due to COPD worsening as any diagnosis, AND 2) with systemic steroids and/or antibiotics prescription.
PrimaryTime to First Chronic Obstructive Pulmonary Disease (COPD) Exacerbation Event From the Index DateUp to 12 months from the index date. Index date was between 01 January 2005 and 30 April 2015.
Mean and Standard Deviation of time to first COPD exacerbation (moderate or severe) event from the index date was estimated using the Kaplan-Meier curve.
