Table 1.
Risk ratio (RR), 95% confidence interval (CI) and p-values for reported rotavirus infections per 1°C increase in mean weekly temperature over lags of 0–4 weeks. Regression coefficient, 95% CI and p-values for the infection-rate parameter per 1°C increase in mean weekly temperature. Temperature thresholds were estimated where there was statistical evidence at the 5% level of a nonlinear relationship.
