The prevalence of proteinuria for the (a) in-hospital survival group (living, n = 281) and mortality group (dead, n = 42) and (b) 90-day survival group (living, n = 277) and mortality group (dead, n = 46) during the ICU admission day and postoperative days 1, 7, and 14. The prevalence of proteinuria significantly increased during this period among the in-hospital and 90-day mortality groups but not in the survivor groups (* P < 0.05)
