Abstract

Context: The diagnosis of Cushing’s syndrome (CS) requires the use of tests of unregulated hypercortisolism that have unclear accuracy. Objective: Our objective was to summarize evidence on the accuracy of common tests for diagnosing CS. Data Sources: We searched electronic databases (MEDLINE, EMBASE, Web of Science, Scopus, and citation search for key articles) from 1975 through September 2007 and sought additional references from experts. Study Selection: Eligible studies reported on the accuracy of urinary free cortisol (UFC), dexamethasone suppression test (DST), and midnight cortisol assays vs. reference standard in patients suspected of CS. Data Extraction: Reviewers working in duplicate and independently extracted study characteristics and quality and data to estimate the likelihood ratio (LR) and the 95% confidence interval (CI) for each result. Data Synthesis: We found 27 eligible studies, with a high prevalence [794 (9.2%) of 8631 patients had CS] and severity of CS. The tests had similar accuracy: UFC (n = 14 studies; LR+ 10.6, CI 5.5–20.5; LR− 0.16, CI 0.08–0.33), salivary midnight cortisol (n = 4; LR+ 8.8, CI 3.5–21.8; LR− 0.07, CI 0–1.2), and the 1-mg overnight DST (n = 14; LR+ 16.4, CI 9.3–28.8; LR− 0.06, CI 0.03–0.14). Combined testing strategies (e.g. a positive result in both UFC and 1-mg overnight DST) had similar diagnostic accuracy (n = 3; LR+ 15.4, CI 0.7–358; LR− 0.11, CI 0.007–1.57). Conclusions: Commonly used tests to diagnose CS appear highly accurate in referral practices with samples enriched with patients with CS. Their performance in usual clinical practice remains unclear.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
