Laparoscopic gastric bypass vs. sleeve gastrectomy in the super obese patient: early outcomes of an observational study.
Observational study in Obesity surgery, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 35 papers, 8 of them syntheses 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
backgroundSuper obesity [body mass index (BMI) > 50 kg/m2] can yield to higher morbidity/mortality in bariatric surgery, this could be related to patient's characteristics and/or surgeon's experience. In morbid obesity, both techniques proved to have a positive impact and sometimes comparable outcomes during the first 2 years. This has not been clearly analyzed in the super obese patient.
methodsRetrospective study comparing the records of 77 consecutive super obese patients (BMI: 50-59.9 kg/m2) submitted to either laparoscopic gastric bypass (LGBP, n = 32) or laparoscopic sleeve gastrectomy (LSG, n = 45) between 2010 and 2012 at a single institution. The primary objective was to analyze baseline demographics, comorbidities, operative outcomes, and early complications (<30 days). Secondarily, weight loss [BMI and % excess weight loss (%EWL)] was also described and compared during the first year.
resultsFemale sex comprised 72.7 % of all cases. Both groups had comparable BMI (52.7 ± 2.1 kg/m2 for LGBP vs. 53.87 ± 2.8 kg/m2 for LSG; p = 0.087) and homogeneous baseline characteristics. Operative time was lower for the LSG group (113.1 ± 35.3 vs. 186.9 ± 39 min for LGBP; p ≤ 0.001). Overall, early complications were observed in 16.8% of patients (LGBP 9% vs. LSG 22%; p = 0.217). There were four major complications (two in each group), with two reinterventions. Weight loss (%EWL) at 6, 9, and 12 months was significantly higher in the LGBP group (51.6 ± 12.9%, 56.5 ± 13%, 63.9 ± 13.3%, respectively) than in the LSG group (40 ± 12.8%, 45.1 ± 15.5%, 43.9 ± 10.4%, respectively).
conclusionsJust like in morbid obesity, LGBP and LSG are effective and safe procedures in super obese patients. LGBP had better weight loss at 1 year.
