直接志愿者“eCohort”招募可能是招募大量参与者的有效方式，但可能存在志愿者偏见。我们将 Health eHeart 研究中自选的参与者与 2013-14 年国家健康和营养检查调查 (NHANES)（一项针对美国人口的横断面调查）的参与者进行了比较。与美国人口（5,769 名 NHANES 参与者）相比，拥有完整调查数据的 12,280 名 Health eHeart 参与者中女性的可能性更大（调整后优势比 (ORadj) = 3.1；95% 置信区间 (CI) 2.9-3.5）；与白人/非西班牙裔相比，黑人、西班牙裔或亚裔的可能性较小（ORadj = 0.4-0.6，p < 0.01）；更有可能受过大学教育（ORadj = 15.8 (13-19) 与
Direct volunteer "eCohort" recruitment can be an efficient way of recruiting large numbers of participants, but there is potential for volunteer bias. We compared self-selected participants in the Health eHeart Study to participants in the National Health And Nutrition Examination Survey (NHANES) 2013-14, a cross-sectional survey of the US population. Compared with the US population (represented by 5,769 NHANES participants), the 12,280 Health eHeart participants with complete survey data were more likely to be female (adjusted odds ratio (ORadj) = 3.1; 95% confidence interval (CI) 2.9-3.5); less likely to be Black, Hispanic, or Asian versus White/non-Hispanic (ORadj's = 0.4-0.6, p < 0.01); more likely to be college-educated (ORadj = 15.8 (13-19) versus
