Values are medians (25th–75th percentiles). #P = 0.02 compared with IAP day 2 in survivors. No other significant differenceswere found using the Mann Whitney test (comparing values between groups on specific days) or Wilcoxon’s signed rank test or Friedmans’s test (comparing paired values within groups over 2 or 3 days, resp.). since .
