Table 3.

Overall and random sensitivity and specificity rates, total and partial (specificity >0.8) AUROCs for the various studies grouped by modality. Note: Overall sensitivity and specificity are the expected sensitivity and specificity for all raters, that is, an average of many raters. Therefore, rater variability is eliminated.
