Comparison of the trifecta outcomes of robotic and open nephron-sparing surgeries performed in the robotic era of a single institution

SpringerPlus

Table 4 Univariable and multivariable Cox analyses were performed to identify variables predictive of trifecta positive outcomes in the open surgery group
