Figure 3

Forest plot of the association of Pv DBP IgG responses with Plasmodium vivax infection. Estimates represent the estimate of P. vivax infection in IgG responders compared with non-responders, unless stated otherwise. For cross-sectional studies, the estimate is an odds ratio; for cohort studies, it is a risk ratio. 1Colina study site; 2Ribeirinha study site; 3First (baseline) survey; 4Second survey. aEstimate supplied by the original authors following correspondence; bdata supplied by the original authors and estimate calculated by the current authors; cestimate calculated by the current authors from data in the paper; dpublished estimate. All estimates are unadjusted, with the exception of estimates from Cole-Tobian et al. [34], which were adjusted for age. When I 2 was ≤30%, meta-analysis based on a fixed-effects model was conducted. Estimates for distinct alleles of PvDBPII were not combined in meta-analysis. Abbreviations: AU, antigen units; LM, light microscopy; RTQ-PCR, real-time quantitative polymerase chain reaction; PNG, Papua New Guinea; W, weight.
