Figure 19 presents a summary receiver operating characteristic (SROC) curve demonstrating an average sensitivity of 77 percent (95% CI, 65 to 85%) and specificity of 89 percent (95% CI, 76 to 95%). The ROC curve illustrates the tradeoff between sensitivity and specificity since the threshold that defines a positive test result varies from the most stringent to the least stringent. Open circles represent individual study estimates of sensitivity and specificity. The black circle indicates the average sensitivity and specificity estimate of the study results, and the dashed circle represents the 95 percent confidence region around it.
