Figure 1  Flowchart of included studies.

Figure 2 Receiver operating characteristic curve and forest plots of sensitivity and specificity. A and B: In differentiating sessile serrated lesions (SSLs) from non-SSLs; A: Summary receiver operating characteristic curve for differentiating SSLs from non-SSLs; B: Forest plots of sensitivity and specificity in differentiating SSLs from non-SSLs; C and D: In differentiating SSLs from hyperplastic polyps (HPs); C: Summary receiver operating characteristic curve for differentiating SSLs from HPs; D: Forest plots of sensitivity and specificity in differentiating SSLs from HPs. SROC: Summary receiver operating characteristic; SENS: Sensitivity; SPEC: Specificity; AUC: Area under the curve; CI: Confidence interval.
