Comparison of peri- and intraoperative outcomes of open vs robotic-assisted partial nephrectomy for renal cell carcinoma: a propensity-matched analysis

Table 3 Multivariable linear regression models (estimated blood loss, LOS) and multivariable logistic regression models (intraoperative complication, postoperative complication, trifecta) in 615 patients treated with open (n=481) or roboticassisted partial nephrectomy (n=134) for renal cell carcinoma at a tertiary care center from 01/2003 to 01/2021
