The forest plots for estimating overall specificity (top chart) and sensitivity (bottom chart) of LAMP method. According to the included studies, the sensitivity and specificity were presented as 95 percent confidence intervals. The red vertical lines show either the overall sensitivity or specificity. The non-significant p-values of I² showed that there was no evidence of heterogeneity between the studies. According to the sample sizes of studies, the sizes of the black squares show the weight of each study. TN: true negative; FP: false positive
