Outcomes among open, laparoscopic and robotic approaches.

Table 2: Outcomes among open, laparoscopic and robotic approaches.

	Laparoscopic n = 829	Robotic n = 488
90-Day Complication Rate, %^a
Major (Clavien III - V)	12.7	21.5
Operating Room Time (minutes)^b
Median (IQR)	252 (194.5)	363 (180)^*
Length of Stay (days)^c
Median (IQR)	6 (6)	6 (6)
90-Day Readmission Rate, %^a	8.1	13.8

IQR: interquartile range; ^a: Chi-square test was used; ^b: Quantile regression analysis was used (reference group: laparoscopic approach); ^c: Negative binomial regression analysis was used (reference group: laparoscopic approach);

^*: p < 0.05.
