Results of regression analyses of hydroclimatic risk factors for human leptospirosis incidence at the weekly timescale and county resolution, encompassing the transmission season of leptospirosis in Sichuan (August-October).

Incidence rate ratios (IRR) and 95% confidence intervals (CIs), were estimated using quasi-Poisson regression and the robust sandwich estimator for variance and correspond to an increase in exposure equivalent to the interquartile range of the variable (4.36 mm precipitation (P); 3.39 mm soil moisture (θ)). Reference values for the each of the exposure variables are presented in Table 2. Bolded values correspond to associations that are statistically significant at the 95% confidence level. Information supporting variable selection can be found in S1 Text. Results for regression including other hydroclimatic predictors are included in S2 Table.
