Fig. 1From: Effects of preoperative high-oral protein loading on short- and long-term renal outcomes following cardiac surgery: a cohort studyChanges in eGFR. eGFR by study day for patients receiving preoperative protein loading or standard preoperative care, change from preoperative values. p < 0.001 for the interaction day:group. Light grey: patients receiving standard preoperative care; dark grey: patients receiving preoperative high-oral protein load. The points are mean values with error bars, indicating the 95% confidence intervals. eGFR, estimated glomerular filtration rateBack to article page
