Bilateral inferior petrosal sinus sampling (BIPSS) is the gold standard for this differentiation, but false-negative results can limit its accuracy. Adding prolactin (PRL) measurement to BIPSS has been proposed to improve diagnostic precision. This meta-analysis evaluates how correction for prolactin levels ('prolactin adjustment') affects the diagnostic value of BIPSS in distinguishing Cushing's disease from ectopic ACTH syndrome.</p><p><strong>Methods: </strong>A systematic literature search was conducted in PubMed, Scopus, EMBASE, Web of Science, and Google Scholar up to July 2024.
