Comparison of robotic and laparoscopic rectal cancer surgery: a meta-analysis of randomized controlled trials.
Synthesis in World journal of surgical oncology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 46 papers, 11 of them syntheses that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveRobotic and laparoscopic surgery for rectal cancer has been applied in the clinic for decades; nevertheless, which surgical approach has a lower rate of postoperative complications is still inconclusive. Therefore, the aim of this meta-analysis was to compare the postoperative complications within 30 days between robotic and laparoscopic rectal cancer surgery based on randomized controlled trials.
methodsRandomized controlled trials (until May 2020) that compared robotic and laparoscopic rectal cancer surgery were searched through PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, and China Biology Medicine disc (CBMdisc). Data regarding sample size, clinical and demographic characteristics, and postoperative complications within 30 days, including overall postoperative complications, severe postoperative complications (Clavien-Dindo score ≥ III), anastomotic leakage, surgical site infection, bleeding, ileus, urinary complications, respiratory complications, conversion to open surgery, unscheduled reoperation, perioperative mortality, and pathological outcomes, were extracted. The results were analyzed using RevMan v5.3.
resultsSeven randomized controlled trials that included 507 robotic and 516 laparoscopic rectal cancer surgery cases were included. Meta-analysis showed that the overall postoperative complications within 30 days [Z = 1.1, OR = 1.18, 95% CI (0.88-1.57), P = 0.27], severe postoperative complications [Z = 0.22, OR = 1.12, 95% CI (0.41-3.07), P = 0.83], anastomotic leakage [Z = 0.96, OR = 1.27, 95% CI (0.78-2.08), P = 0.34], surgical site infection [Z = 0.18, OR = 1.05, 95% CI (0.61-1.79), P = 0.86], bleeding [Z = 0.19, OR = 0.89, 95% CI (0.27-2.97), P = 0.85], ileus [Z = 1.47, OR = 0.66, 95% CI (0.38-1.15), P = 0.14], urinary complications [Z = 0.66, OR = 1.22, 95% CI (0.67-2.22), P = 0.51], respiratory complications [Z = 0.84, OR = 0.64, 95% CI (0.22-1.82), P = 0.40], conversion to open surgery [Z = 1.73, OR = 0.61, 95% CI (0.35-1.07), P = 0.08], unscheduled reoperation [Z = 0.14, OR = 0.91, 95% CI (0.26-3.20), P = 0.89], perioperative mortality [Z = 0.28, OR = 0.79, 95% CI (0.15-4.12), P = 0.78], and pathological outcomes were similar between robotic and laparoscopic rectal surgery.
conclusionRobotic surgery for rectal cancer was comparable to laparoscopic surgery with respect to postoperative complications within 30 days.
