| Yes | No | Unclear | ||
| 1 | Was the spectrum of patients representative of the patients who will receive the test in practice? | () | () | () |
| 2 | Were the selection criteria clearly described? | () | () | () |
| 3 | Is there a diagnostic reference standard? | () | () | () |
| 4 | If so, is the reference standard likely to correctly classify the target condition? | () | () | () |
| 5 | Is the time period between reference standard and index test short enough to be reasonably sure that the target condition did not change between the two tests? | () | () | () |
| 6 | Did the whole sample or a random selection of sample, receive verification using a reference standard of diagnosis? | () | () | () |
| 7 | Was the execution of the index test described in sufficient detail to permit replication of the test? | () | () | () |
| 8 | Was the execution of the reference standard described in sufficient detail to permit replication of the test? | () | () | () |
| 9 | Were the index test results interpreted without knowledge of the results of the reference standard? | () | () | () |
| 10 | Were the reference standard results interpreted without knowledge of the results of the index test? | () | () | () |
| 11 | Were the same clinical data available when test results were interpreted as would be available when the test is used in practice? | () | () | () |
| 12 | Were uninterpretable/intermediate results reported? | () | () | () |
| 13 | Were withdrawals from the study explained? | () | () | () |
| 14 | Are data presented on observer or instrument variation that could affect the estimates of test performance? | () | () | () |
| 15 | Were appropriate results presented (percentage of correct diagnoses, sensitivity, specificity, predictive values, measures of ROC, likelihood ratios, or other relevant measures) and were these calculated appropriately? | () | () | () |
