FIG 2.

Forest plots of sensitivity and specificity of self-collected swabs compared to investigator-collected swabs with pooled estimates of sensitivity and specificity. Shown are sensitivity and specificity from each study (black dots in gray squares), corresponding 95% confidence intervals, and overall summary estimates for sensitivity and specificity (clear diamonds) calculated by bivariate random-effects meta-analysis. HCW, health care worker; SOF, supervised oral fluid; UOF, unsupervised oral fluid; NP, nasopharyngeal; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
