Fig 6. Forest plot of the random effect meta-analysis of MG prevalence (%) calculated based on the results from PCR.
Blue squares represent prevalence of MG of individual studies; the size of each blue square represents the weight of the individual study in calculating average prevalence; horizontal lines represent 95% Wilson confidence intervals (%) of the prevalence from individual studies; the gray diamond and vertical dotted line represent average prevalence calculated using the random-effects model; and I2 and τ2 statistics describe the heterogeneity of the studies with p-value of the heterogeneity test.
