Robotic-assisted low anterior resection for rectal cancer shows similar clinical efficacy to laparoscopic surgery: A propensity score matched study

Figure 1 Univariate and multivariate analysis of anastomotic leakage (Clavien-Dindo grade ≥ II). A: Univariate analysis; B: Multivariate analysis. BMI: Body mass index; ASA: American Society of Anesthesiologists. NYHA: New York Heart Association; 95%CI: 95% confidence interval; OR: Odds ratio.

Figure 2 The 3-year overall survival and disease-free survival rate between robotic and laparoscopic surgical procedures. A: Overall survival (OS) rate for all stages in both groups; B: OS rate for stage I in both groups. In stage I, the Log-rank test could not calculate a meaningful statistic or P value; C: OS rate for stage II in both groups; D: OS rate for stage III in both groups; E: Disease-free survival (DFS) rate for all stages in both groups; F: DFS rate for stage I in both groups; G: DFS rate for stage II in both groups; H: DFS rate for stage III in both groups. RALAR: Robot-assisted low anterior resection; LALAR: Laparoscopic-assisted low anterior resection; OS: Overall survival.
