description: Additional file 1: Table S0. Demographic characteristics of study schools. We present the number of participating and observed students. Distinction is made between kindergarten students enrolled in full-time and half-day programs in schools which operate such programs. Table S1. Grade-specific contact rates. Table S2. Unobservable students with (enrolled students for whom we could not complete a telephone follow-up upon their absence) and number of absence and characterizable absence events made by enrolled students, stratified by school, grade and sex. Table S3. Forward model selection process. Table S4. Final models identified using the forward selection process. Table S5. Odds ratios$ of ILI, any virus, influenza (A or B), influenza A, influenza B on grade within all schools where kindergarteners were taught for half-days (schools B1, B3, B4, B5, and B6). Table S6. Odds ratios$ of ILI, any virus, influenza (A or B), influenza A, influenza B on duration of instruction within schools with any kindergarteners taught for half-days (schools B1, B3, B4, B5, and B6). Table S7. Odds ratios$ of ILI, any virus, influenza (A or B), influenza A, influenza B on length of school instruction, grade, sex, and self-reported vaccination status among schoolchildren in schools with both half and full day Kindergarteners (schools B1, B3, B4, and B5). As all the schools belonged to the same school district, only a random effect term for school was included in the models. Variables significant at the 95% level are shown in bold. Table S8. Association between testing positive according to four different outcomes and delay in swabbing (delay between symptom onset and swab taken). Figure S1. Cumulative attack rate for influenza type A and B, by grade and district. Figure S2. Cumulative attack rates, stratified by grade and school, for other respiratory viruses. Figure S3. Cumulative attack rate (CAR) by infection outcome (columns), stratified by grade and school (rows). Figure S4. Relationship between the proportion of samples testing positive for virus and the delay between symptom onset date and swabbing date. Figure S5 Spline of secular time fitted using a negative binomial GAM of swabbing delay.
