Comparison of the sensitivity, specificity and likelihood ratio of tests.

p-ELISA = enzyme immunoassay with antigens of promastigotes of Leishmania sp. DAT = direct agglutination test, IFAT = indirect immunofluorescence; rK39-ELISA = enzyme immunoassay with rK39 antigen, n = number of studies included in the analysis, S = sensitivity, Sp = specificity; LR+ = positive likelihood ratio, LR− = negative likelihood ratio. CI = confidence interval.*Analysis in which the study by Romero et al. was excluded because of discrepancies noted in the published data.
