SHAM group 什么意思，论文里出现的SHAM group是什么意思？sham operation是假手术模拟手术的意思，可以理解为空白对照组嘛？

Answer 1

SHAM group可翻译成假手术组；对照组；空白对照组，对于这种专业的东西我也不是很了解，以下是几个例子，希望对您有帮助： 1.The calcium node in PEMFs group was far more than that in sham group. 钙结节数量实验组也明显多于对照组。 2.In addition, 24% of patients in the active group and 28% in the sham group reported vomiting. 此外，治疗组的病患有24%、对照组有28%的病患报告有呕吐。 3.Results. None of the animals in the sham group showed a significant change in firing due to venous stasis. 结果：假手术组没有一只由于静脉停滞产生明显的发作变化。 4.Methods : Twenty-four rats were divided into 4 groups : blank group, model group, sham operation group and electric acupuncture group. 方法：将健康大鼠随机分为正常组（空白对照组）、模型组、假手术组和电针治疗组。 5.Method: SD rats were randomly divided into normal group, sham operation group, TWP control group, model group, saline group, TWP low dose group and TWP high dose group. 方法：SD大鼠随机分为正常组、假手术组、药物对照组、模型组、生理盐水组、雷公藤多甙低、高剂量组。
