the odds ratios for death for each 2-point increase on the infection score were within the 95% CIs of the odds ratios for death for most of the other components of the SOFA score (Table 1). Thus, the infection score was given the same weight as the other components of the SOFA score (Table 2). Table 3 gives the distributions of ear- lier infection points for patients in the derivation and validation cohorts.
