aAnalysis of variance or chi-square comparing the three study periods; period I is used as reference. bScores for the Sequential Organ Failure Assessment (SOFA) can range from 0 to 24, with higher scores indicating a higher risk of death. CI, confidence interval; ICU, intensive care unit; OR, odds ratio; SD, standard deviation. | ||||
