Weight loss before bariatric surgery and its impact on poor versus excellent outcomes at 2 years.
Article in Langenbeck's archives of surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
purposeTo identify preoperative factors that influence the outcomes of gastric bypass surgery, in terms of excess weight loss at 24 months.
methodsThis retrospective study included two groups of patients who underwent laparoscopic gastric bypass surgery. Group A (poor outcomes) had ≤ 50%EWL or BMI ≥ 30 kg/m
resultsA total of 202 patients completed follow-up; 71 (35.1%) and 78 (38%) had poor and excellent outcomes (%EWL 44.1 ± 9.4% vs. 92 ± 10.9%), respectively. Mean age was 40.4 ± 8.9 years. Patients with poor outcomes had higher weight and BMI, lesser preoperative %EWL, higher dyslipidemia and diabetes rates with longer periods of evolution, and increased HbA1c% levels. In the linear regression analysis, preoperative %EWL and initial and preoperative BMI were statistically significant determinants of %EWL at 24 months Diabetes remission was 46.2% (group A) vs. 66.6% (group B). Group A had higher non-attendance rates after surgery.
conclusionThe factors independently associated with greater %EWL at 24 months between groups were higher preoperative %EWL, and lower initial and preoperative BMI.
