Table 1. Association between the monthly proportion of rotavirus infection and underweight, stunting, wasting for under-5 children in urban Dhaka, Bangladesh.
Adjusted and unadjusted seasonal ARIMA models were fitted to the proportion of children with rotavirus infection. Covariates are outlined in the model definitions below.

Outcome: Proportion of rotavirus infection; main exposure: proportion of underweight/stunting/wasting
Model 1: Unadjusted+ mean centred monthly temperature, rainfall, sea level pressure, humidity
Model 2: Model 1 + year strata (1993–2002 vs. 2003–2012)
Model 3: Model 2 + mean age, proportion female, use non-sanitary toilet, non-slum residence, more than one under 5 year children in the household
Note: All estimates were in monthly basis; Centre value of underweight, mean temperature, rainfall, sea level pressure, humidity were used
