Five-year outcomes after surgery for class 1 obesity: a retrospective analysis of a Canadian bariatric centre's experience.
Article in Canadian journal of surgery. Journal canadien de chirurgie. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundThere is a paucity of literature exploring the role of bariatric surgery in class 1 obesity. We evaluated the 5-year outcomes after bariatric surgery in patients with class 1 obesity, assessing weight loss, resolution/reduction of obesity-related comorbidities, morbidity and mortality.
methodsWe performed a single-centre retrospective analysis of patients who underwent bariatric surgery (laparoscopic sleeve gastrectomy [LSG] or laparoscopic Roux-en-Y gastric bypass [LRYGB)]) for class 1 obesity (body mass index [BMI] 30.0-34.9) between January 2012 and February 2019.
resultsThirty-seven patients (35 [95%] female, mean age 44.5 yr [standard error (SE) 11.3 yr], mean preoperative BMI 33.1) were included, of whom 32 underwent LSG and 5 underwent LRYGB. Thirty-five patients were followed for 5 years post-operatively, achieving a mean BMI of 25.6 (SE 1.2) and excess weight loss of 89.4% (SE 15.1%). Remission of hypertension was achieved in 5 of 12 patients (42%), and remission of dyslipidemia was achieved in 7 of 11 patients (64%). Of the 11 patients with diabetes, 7 underwent LSG and 4, LRYGB. At 5 years postoperatively, the mean glycosylated hemoglobin concentration was 6.3%. Four patients in the LSG group developed de novo reflux, 1 patient required conversion to LRYGB, and 1 patient with sleeve stenosis required endoscopic dilatation. There were no deaths in either patient group.
conclusionAt our centre, bariatric surgery for class 1 obesity was safe and had long-term efficacy, with remission or reduction of related comorbidities. Prospective controlled trials are required to confirm these results.
