Screening tests are done to diagnose asymptomatic disease in apparently healthy people with the aim to reduce mortality and morbidity from the disease. Certain criteria need to be fulfilled before we adopt population-level screening for any disease. Several biases exist in evaluating screening studies, and the ideal study design would be a randomized trial with hard endpoints such as mortality and morbidity.
筛查测试是为了在看似健康的人群中诊断无症状疾病,目的是降低该疾病的死亡率和发病率。在我们对任何疾病采用人群水平的筛查之前,需要满足某些标准。在评估筛查研究时存在几种偏倚,理想的研究设计是采用具有死亡率和发病率等硬终点的随机试验。
