Official title

CSP #597 - Diuretic Comparison Project

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The Diuretic Comparison Project aimed to evaluate whether chlorthalidone, as compared with hydrochlorothiazide, would reduce the risk of major nonfatal cardiovascular disease outcomes and non-cancer-related deaths in older patients with hypertension who were receiving hydrochlorothiazide at baseline. The investigators incorporated the pragmatic methods used by the Department of Veterans Affairs (VA) Healthcare System to provide a real-world assessment of the effectiveness of chlorthalidone as compared with hydrochlorothiazide in routine clinical care.
