  1. The values in the table represent the number of cases classified as hypothermic in the test set. A tPS > 3 (Y-pred of 0.7), correspond to a sensitivity of 75% and a specificity 100% based on the hypothermia cases in the validation set. The number in brackets after each value represents the total count of cases with the same primary cause of death in the test set. In the test set, 5 cases had hypothermia as contributing cause of death, each of these 5 cases was predicted as a hypothermia case.
