The sensitivity and specificity of the PSA test at selected threshold PSA levels, after adjustment for verification bias, are shown in Table 2. The sensitivity and specificity for threshold values ...

When developing diagnostic tests or evaluating results, it is important to understand how reliable those tests and therefore the results you are obtaining are. By using samples of known disease status ...

Sensitivity and specificity estimates were corrected for verification bias. ... Table 2 shows group-specific estimates of screening-test results with 95% confidence intervals.

Background: Sensitivity and specificity are characteristics of a diagnostic test and are not expected to change as the prevalence of the target condition changes. We sought to evaluate the association ...

Generally, however, a trade-off must be made between sensitivity and specificity. ... sensitivity of 15-67% has been reported at a specificity of >90% (Table 4).

Table 3 Sensitivity and specificity by the detection method according to histological type, smoking status and rank of screening; (a) low-dose CT group and (b) chest X-ray group.

Now, 100% sensitivity and 95% specificity have a very different meaning. In a group of 100,000 patients, the algorithm would detect the rare tumors in only 5,000 scans.

Background: Anecdotal evidence suggests that the sensitivity and specificity of a diagnostic test may vary with disease prevalence. Our objective was to investigate the associations between disease ...

Table 2 shows sensitivity, specificity, PPV and NPV for the FFQ compared to overall use of any as well as of specific dietary supplements (multivitamins, vitamin C, E, ...

Youden's J-value was calculated from the calculated sensitivity and specificity of each test ( Table 2). ... (93.7 and 100%, respectively), but had low specificity ( Table 4).
