Table 5 Subgroup meta-analysisa of studies reporting proportion of minimum infection rates (MIR) in vectors grouped by mosquito species. Each effect size (computed for the group of studies reporting proportion of JEV in each mosquito species) represents pooled estimates (effect size) of the outcome for each mosquito species, and the overall represents the overall pooled estimate across all mosquito species

From: Meta-analyses of the proportion of Japanese encephalitis virus infection in vectors and vertebrate hosts
