Calculated by ConductScience from the counts the trial posted to ClinicalTrials.gov.
| Measure | Value | 95% interval, lower | 95% interval, upper | Method | Note |
|---|---|---|---|---|---|
| Risk in group 1 | 0 | 0 | 0.125 | wilson | |

Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Penicillin Allergic Floor Patients Who Received Amoxicillin Challenge - Experimental | Patients in the intervention group who received an amoxicillin challenge.~The intervention will provide access to a best-practices alert containing a penicillin allergy risk stratification tool and recommendations on whether to use an oral amoxicillin test dose challenge order set for patients who stratify as low risk.~Penicillin Allergic Risk Stratification Best Practice Alert: Providing best practice information on a patient's penicillin allergy risk and how to manage different levels of risk. | 0 | 27 | OG000 |
| Group 2 | Penicillin Allergic Floor Patients Who Received Amoxicillin Challenge - Control | Patients in the control group who received an amoxicillin challenge.~Patients will receive current standard of care for penicillin allergy, which typically involves physician judgement on challenges versus consultation of allergy service. | 0 | 21 | OG001 |
