IR = Incidence rate; IRR = incidence rate ratio; 95%CI = 95% Confidence interval;
*
For all 95% CIs, generalized estimating equations were used to account for clustering at the clinic level. IR and IRR were estimated using piecewise Poisson models with intervals between study visits as a categorical time variable.
†
Incidence rate for median age (27 years old).
