2. Fig
Score chart for the 1-year and 5-year predicted risk of a cardiovascular event. The exact survival estimate can be calculated by S(t) = S0(t)exp(LP), where the linear predictor (LP) is β1 × x1 + β2 × x2 + …, with x denoting the predictor and β the regression coefficient (Table III), and t is the time point of interest.
