Mean sensitivity increased from 50% to 81%, an improvement of 63% in the number of cancer cases identified (25.4 vs. 41.4, F(1, 1,161) = 165.95, p \u003c 0.001). Specificity (60–58%; 30.7 vs. 29.1, F(1, 1,161) = 1.11, p = 0.29), PPV (mean = 47–67%; F(1, 1,297) = 0.02, p = 0.89), and NPV (mean = 65–75%; F(1, 933) = 0.61, p = 0.44) did not change significantly
