eGFR among patients receiving a high-oral protein load compared to those receiving standard preoperative care. a eGFR at the time of admission as well at 3 and 12 months after surgery. b Change in eGFR relative to the time of admission. 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. The number of patients at different time points for each group are provided in parentheses. eGFR, estimated glomerular filtration rate
