a
Adjusted for region, practice type, baseline antibiotic prescribing, the perceived parental expectation for antibiotics, indication for antibiotics, child’s age, and fever.
b
2191 infectious episodes analysed (36 episodes [1.6%] excluded because of missing information about temperature). AOR = adjusted odds ratio. BISNA = brief intervention with safety net. CRP = C-reactive protein. OR = odds ratio. POC = point-of-care.
