A critical appraisal and clinical application of: DeVore GR, Owens O, Kase N. Use of intravenous Premarin in the treatment of dysfunctional uterine bleeding--a double-blind randomized control study. Obstet Gynecol. 1982 Mar;59(3):285-91.
This appraisal identifies significant statistical irregularities in the study. A reworking of the study's statistics leads to a conclusion different from that put forth by the authors of this paper: intravenous estrogen therapy is not, in fact, significantly more effective compared to placebo therapy for the cessation of acute abnormal uterine bleeding.
