Relationship between observed and predicted mortality by total score. Predicted mortality was estimated based on logistic regression model of two thirds of the cohort (development sample). Observed mortality was depicted from the remaining one third of the cohort (test sample). Coefficient of correlation between observed and predicted mortality r2 = Number of observations in the test sample by score: 1 – 3229, 2 – 2497, 3 – 4051, 4 – 2573, 5 – 2135, 6 – 1555, 7 – 1104, 8 – 800, 9 – 475, 10 – 312, 11 – 186, 12 – 130, 13 – 69, 14 – 24, 15 – 31, 16 – 15, 17 – 11, 18 – 2, 19 – 0, 20 – 3.
