Thirty-two family physicians in British Columbia collaborated in a study to evaluate their patients' compliance when offered testing for fecal occult blood (FOB) with Hemoccult II as a screening test for asymptomatic colorectal cancer. Of the 5003 eligible patients 71% complied. Thirteen variables were investigated. Compliance was found to be directly related to age in a linear manner (chi-squared value for trend = 180.4, p less than 0.0001), age alone correctly classifying 58.5% of the patients as complying or not complying. The association with other variables was less strong. Restricting the consumption of red meat during the test period had no effect on compliance.
不列颠哥伦比亚省的32位家庭医生合作开展了一项研究，以评估当为患者提供便潜血（FOB）检测（使用Hemoccult II作为无症状结直肠癌的筛查测试）时患者的依从性。在5003名符合条件的患者中，71%的患者依从。研究调查了13个变量。发现依从性与年龄呈直接线性关系（趋势的卡方值 = 180.4，p < 0.0001），仅年龄就能正确地将58.5%的患者分类为依从或不依从。与其他变量的关联则没那么强。在测试期间限制红肉的摄入量对依从性没有影响。
