In this clinical trial, 786 patients screened for colorectal cancer with fecal occult blood testing were assigned to either a "diet" or "no diet" group to examine the effect of advice to restrict intake of red meat and peroxidase-containing vegetables on patient compliance and positivity rates. Restrictive diets did not significantly decrease compliance. Interviews of patients in the "diet" group demonstrated that the majority followed instructions. Positivity rates were similar in the two groups, and clinically significant lesions were found with comparable frequency.
在这项临床试验中,786名接受粪便潜血检测以筛查结直肠癌的患者被分为“饮食”组或“非饮食”组,以研究限制红肉和含过氧化物酶蔬菜摄入量的建议对患者依从性和阳性率的影响。限制性饮食并未显著降低依从性。对“饮食”组患者的访谈表明,大多数患者遵循了指示。两组的阳性率相似,且发现具有临床意义病变的频率相当。
