The study aims to show advantages of the nested case-control design for diagnostic accuracy studies.

The nested case-control study is a valid and efficient design for diagnostic studies and should be considered in current guidelines.

The nested case-control design can reduce patient burden and save resources.
Diagnostic accuracy estimates from nested case-control samples were similar to those from the full study population.
The study included 289 cases of DVT and 1006 controls.

This study shows that using a special way to pick patients for tests can help doctors get better results without needing to test everyone.

Data from a full cross-sectional diagnostic study of 1295 patients suspected of DVT was used to draw nested case-control samples.

Potential biases in conventional case-control designs were discussed, emphasizing the advantages of the nested approach.

The study design may not be applicable in all diagnostic contexts and relies on the correct identification of the source population.

Adult patients suspected of deep vein thrombosis, with a mean age of 61.9 years.

95% confidence intervals were reported for diagnostic accuracy measures.
