  Figure 2. Forest Plots for the Pooled Sensitivity and Specificity of the Studies (A) Forest plots for pooled sensitivity of the studies. Horizontal lines represent 95% CIs of the individual studies. (B) Forest plots for pooled specificity of the studies. Horizontal lines represent 95% CIs of the individual studies. TN = true negative; FP = false positive; TP = true positive; FN = false negative.

  Figure 4. Subgroup Analysis (A) Subgroup analysis of studies for sensitivity based on inclusion of AF participants. Horizontal lines represent 95% CIs of the individual studies. (B) Subgroup analysis for specificity based on inclusion criteria of studies. Horizontal lines represent 95% CIs of the individual studies. TN = true negative; FP = false positive; TP = true positive; FN = false negative.
