Abstract:
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.
