CI = confidence interval; EBL = estimated blood loss; eGFR = estimated glomerular filtration rate; IQR = interquartile range.

β represents the value increase for the outcome per 1-point increase in nephrometry score. For example, a 1-point increase in RENAL score would result, on average, in a 33.8-ml increase in EBL.
