Appendix Figure 3. HSROC curve of the sensitivity versus specificity of fecal immunochemical tests for the detection of colorectal cancer for all included studies.
The circles represent the data from each included study, the straight line represents the curve, and the diamond represents the summary point of the curve to which the pooled sensitivity and specificity correspond. The dashed line represents the 95% confidence area for the summary point, and the dotted line represents the 95% confidence area in which a new diagnostic accuracy fecal immunochemical test study will be located. AUC = area under the curve; SENS = sensitivity; SPEC = specificity; HSROC = hierarchical summary receiver-operating characteristic.
