Table 8 Univariable meta-regression model for minimum infection rates (MIR). Coefficients, P-values, and 95% confidence intervals (CI) of the association between predictors of interest with minimum infection rates (MIR) in vectors (n = 16 studies). Random effects meta-regression models use the restricted maximum likelihood method (REML)
