Table 7 Multivariable meta-regression model for the proportion of JEV infection in vertebrate hosts. Coefficients, P-values, and 95% confidence intervals (CI) of the association between predictors of interest with the proportion of JEV infection in vertebrate hosts (n = 33 studies). Random effects meta-regression models use the restricted maximum likelihood method (REML)
