Respiratory Hospitalization
Crude IRR (95%CI)	42	6309	8	7251	0.33 (0.11, 0.98)	9	6206	0.39 (0.12, 1.32)
Adjusted IRR (95%CI) ^†					0.34 (0.12, 1.02)			0.48 (0.16, 1.40)

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.
