Estimates for men and women were collapsed because of comparability in incidence and survival statistics.
Incidence and survival data were used to reflect Wilson and Jungner's first criterion (ie, whether the disease at hand is an important health problem). For incidence: +: <10, ++: >10, <100, +++: >100 per 100 000. For survival: +: >75%, ++: <75%, >50%, +++: <50%.
Incidence directly affected by screening (downwards for cervix and upwards for prostate).
Includes only tests that have been in widespread use and/or have clinical application in specific circumstances. Diagnostic work‐up procedures not considered.
Includes management decisions and diagnostic work‐up.
Considers psychological harms and potential morbidity and risks during the entire screening process, including diagnostic work‐up and treatment.
Cancers for which organized, guideline‐driven screening programs currently exist were considered highly cost‐effective (ie, ++). Cancers for which screening guidelines exist for high‐risk subgroups only, or in opportunistic settings were considered moderately cost‐effective (ie, +). Uncertainty regarding the cost‐effectiveness of screening was considered equivocally cost‐effective (ie, +/−).
