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

Table 4 Multivariable linear regression models (estimated blood loss, LOS) and multivariable logistic regression models (intraoperative complication, postoperative complication, trifecta) in 306 patients treated with open (n=204) or roboticassisted partial nephrectomy (n=102) for renal cell carcinoma at a tertiary care center from 01/2003 to 01/2021 after propensity score matching
