Robotic and laparoscopic Roux-en-Y gastric bypass after learning curve: 30-day and 12-month outcomes.
Review in Journal of robotic surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis 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
This study compares laparoscopic RYGB (L-RYGB) and robotic RYGB (R-RYGB) performed by the same team after the learning curve in both approaches. A retrospective cohort study was done, and the surgical outcome was analyzed in 30 days and 12 months for patients with similar characteristics and an equal number of cases in each group (233 cases). Four hundred and sixty-six patients were included in this study. Mean age was 46.8 ± 8.3 years and 2/3 were women. R-RYGB presented a longer operative time (150.7 versus 135.4 min; p < 0.001) with no differences in the length of hospital stay. The main 30-day complications were G-J stricture, leakage, and intraluminal bleeding. The reoperation rate was 1.6% by leakage (G-J anastomosis) and was higher in R-RYGB (2.1 versus 0.4; p = 0.108). The multivariate analysis identified that L-RYGB was the factor independently associated with a LOS longer than 2 days (odds ratio: 4.7, 95% CI: 2.6-8.2, p value < 0.001). At the FU time (12 months), no differences between the groups were found. The outcomes between the groups after the learning curve did not present differences in terms of 30 days and 12 months of FU when same preoperative characteristics and an equal number of cases in each group are considered. L-RYGB was the unique independent factor associated with long LOS.
