The reporting quality of randomized controlled trials in pharmacotherapy for pituitary adenomas

Abstract

Background: Medical therapy has become an increasingly important intervention owing to improvements in the multidisciplinary care for pituitary adenomas (PAs). This study aimed to assess the reporting quality of randomized controlled trials (RCTs) on PAs pharmacotherapy. Methods: RCTs evaluating the efficacy of pharmacotherapy in PAs published in English between January 1, 1974, and December 31, 2022, were searched for and collected from PubMed and MEDLINE. The 2010 Consolidated Standards for Test Reports (CONSORT) statement-based 28 items overall quality score (OQS) was used to evaluate the overall quality of each report. Results: Twenty-seven related RCTs including 1816 patients were retrieved. The median OQS score was 12 (range, 6–19) on a scale of 0 to 28. Important items, such as background, objectives, participants, interventions, and outcomes, were sufficiently reported in 100% (27/27) of the articles. Statistical methods were adequately described in 93% (25/27) of patients. However, RCTs underreported identification as randomized trials in the title (3/27, 11%), sample size, allocation concealment, implementation, ancillary analysis method, and Diagram and Ancillary analyses (1/27, 4%). The OQS of published RCTs has significantly increased since 2010 (P = .012). The multivariate final model showed significant associations between higher OQS and publication since 2010 and enrollment of more than 100 patients. Conclusions: The overall reporting quality of RCTs on pharmacotherapy in PAs was poor, based on the 2010 CONSORT statement. However, we noticed an improvement in the OQS over the years and identified the factors associated with a better report. Increased effort is necessary to raise awareness of these issues among writers, readers, reviewers, and editors.
