Propensity score matching analysis comparing outcomes between primary and revision Roux-en-Y gastric bypass after adjustable gastric banding: a retrospective record-based cohort study.
Article in Surgical endoscopy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundOne-stage revision Roux-en-Y gastric bypass (RRYGB) after Laparoscopic adjustable gastric banding (LAGB) is widely adopted, but its safety is still debated.
objectiveThis study aimed to compare outcomes between primary Roux-en-Y gastric bypass (PRYGB and RRYGB after LAGB.
methodA retrospective record-based cohort study of patients who underwent PRYGB and RRYGB for failed LAGB and completed at least 2 years of follow-up from 2008 to 2019. Propensity score matching (PSM) analysis was conducted to obtain a balanced sample of patients with RRYGB and PRYGB interventions by adjusting for baseline covariates including age and sex.
resultsPatients with PRYGB (n = 558) and RRYGB (n = 156) were included. PSM identified 98 patients for RRYGB and 98 patients for PRYGB. Both cohorts exhibited significant reductions in BMI compared to baseline values (p < 0.001), but reductions were significantly higher in PRYGB compared to those in RRGYB at 6 months (- 10.55 ± 8.54 vs. - 8.38 ± 5.07; p = 0.032), 1-year (- 21.50 ± 8.19 vs. 16.14 ± 6.93; p < 0.001), and 2 years (- 24.02 ± 7.85 vs. - 18.93 ± 6.80; p < 0.001), respectively. A significant improvement in food tolerance from the 1st to the 2nd year was seen after RYGB (p < 0.001). The rates of early and late complications were similar in both cohorts (p = 0.537, p = 1.00). Overall re-intervention rates were 5.1 and 3.1% for RRYGB and PRYGB p = 0.721). Both cohorts exhibited significant improvement in comorbidities after 2 years (p < 0.001).
conclusionsOne-stage RRYGB for failed LAGB is safe and effective with comparable rates of complications, re-interventions, and resolution of associated comorbid conditions compared to PRYGB.
