Note: Both regression models control for patient, facility, and geographic characteristics included in Table 1 of the main text, along with seasonal variation using dummy variables for each 2-month period in the calendar year. See Tables S1 and S2 for detailed regression results. CI, confidence interval; OR, odds ratio.
