Patients were eligible if they were aged 12 months or older, presented with any clinician-diagnosed acute (\u226421 days) respiratory tract infection, and the patient or clinician believed antibiotic treatment was, or might be, necessary. Participants were randomized (1:1) to RM-POCT or usual care. The research team, including those conducting statistical analyses, were unaware of group allocation.
