Survival. This figure shows adjusted survival estimates of the survival curves among patients receiving early or late protein. The Hazard Ratio for death was calculated at 0.83 (95%, CI 0.71–0.97) with a p value of 0.01 using a multivariable Cox regression analysis that controlled for age, sex, weight, parenteral nutrition, mean delivered calories, mean daily protein received after the first 3 days, administration of vasopressors, SOFA score, and total hospital stay.
