C-statistic for different combinations of eligibility criteria. The open squares, circles and triangles represent validations of the ATP III, PCE and Wilson model, respectively. The black circles and triangles represent the performance of the PCE models for Whites and African-Americans, and Wilson models, in the development populations. Lower part: for age, white means a broad age range was included (difference between upper and lower age limit > 30 years), black means a narrow age range was included (difference between upper and lower age limit ≤ 30 years) and grey means age was not reported. For CVD, white means no exclusion of people with CHD or CVD, grey means people with previous CHD events were excluded from the study and black means people with previous CVD events were excluded from the study. For diabetes, cancer and major disease, white means that no restrictions were reported and black means that people with these conditions were excluded. For treatment, white means no restrictions and black means people who were receiving any treatment to lower their risk of CVD (e.g. anti-hypertensives) were excluded from the study
