Group 0 name Corresponds to the control (unexposed) group for case-control studies
The group given a placebo
Group 1 name Corresponds to the case (exposed) group for case-control studies
The group given an azithromycin oral solution
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
1-3-year-olds diagnosed with recurrent asthma-like symptoms from the COPSAC2010 cohort. Exclusion criteria included macrolide allergy, heart, liver, neurological, kidney disease, and or one or more clinical signs of pneumonia. Participants were prescribed a 3-day course of oral azithromycin solution of 10mg/kg per day.
Group 0 sample size Number of subjects in the control (unexposed) group
33
Group 1 sample size Number of subjects in the case (exposed) group
39
Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
none mentioned
