Early Bleeding After Laparoscopic Roux-en-Y Gastric Bypass: Incidence, Risk Factors, and Management - a 21-Year Experience.
Article in Obesity surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
purposeMorbidity and mortality associated with bariatric surgery are considered low. The aim of this study is to assess the incidence, clinical presentation, risk factors, and management of early postoperative bleeding (POB) after laparoscopic Roux-en-Y gastric by-pass (RYGB). MATERIALS AND
methodsRetrospective analysis of prospectively collected data of consecutive patients who underwent RYGB in 2 expert bariatric centers between January 1999 and April 2020, with a common bariatric surgeon.
resultsA total of 2639 patients underwent RYGB and were included in the study. POB occurred in 72 patients (2.7%). Intraluminal bleeding (ILB) was present in 52 (72%) patients and extra-luminal bleeding (ELB) in 20 (28%) patients. POB took place within the first 3 postoperative days in 79% of patients. The most frequent symptom was tachycardia (63%). Abdominal pain was more regularly seen with ILB, compared to ELB (50% vs. 20%, respectively, p = 0.02). Male sex was an independent risk factor of POB on multivariate analysis (p < 0.01). LOS was significantly longer in patients who developed POB (8.3 vs. 3.8 days, p < 0.01). Management was conservative for most cases (68%). Eighteen patients with ILB (35%) and 5 patients with ELB (25%) required reoperation. One patient died from multiorgan failure after staple-line dehiscence of the excluded stomach (mortality 0.04%).
conclusionThe incidence of POB is low, yet it is the most frequent postoperative complication after RYGB. Most POB can be managed conservatively while surgical treatment is required for patients with hemodynamic instability or signs of intestinal obstruction due to an intraluminal clot.
