In a double-blind comparative study conjugated equine oestrogens (USP) (Premarin Intravenous) and saline were administered intravenously to patients undergoing transurethral prostatectomy. This paper proves that the placebo group (saline) displays a tendency, as indicated by two statistical tests, towards a significant increase in the red blood cells lost in the 24-hours after the operation. The Premarin Intravenous group showed no such tendency.
在一项双盲对照研究中，对接受经尿道前列腺切除术的患者静脉注射结合马雌激素（美国药典标准）（倍美力静脉注射液）和生理盐水。本文证明，安慰剂组（生理盐水）经两项统计学检验显示出一种趋势，即术后24小时内流失的红细胞有显著增加的趋势。倍美力静脉注射液组则未显示出这种趋势。
