Study design for paired visit analysis. At time 0 study visit (T0), every participant was a high intensity (HI) injector (≥ 1 injection daily). Injection status over the intervening 6 months was ascertained at the next semiannual visit (T1), and participants were classified based on this latter injection status as HI injectors (continued injection use, ≥ 1 injection daily), reduced intensity (RI) injectors (< 1 injection daily), or cessation (no injection since last visit). Bacterial infection events were ascertained over the 3- and 6-month period following T1
