Quality of life, weight loss and improvement of co-morbidities after primary and revisional laparoscopic roux Y gastric bypass procedure-comparative match pair study.
Article in Obesity surgery, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03341429 (BARI-OPTIMISE), which is not on this map. Cited by 13 papers, 3 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.

Abstract
backgroundThe prevalence of morbid obesity and its co-morbidities is dramatically increasing, as is the extent of weight loss surgery. A large number of patients after various bariatric procedures need revisional intervention for various reasons. We investigated the efficacy and the safety of revisional laparoscopic Roux Y gastric bypass (LRYGB) among our patients, who were revised as a consequence of inadequate weight loss or weight regain after previous bariatric interventions.
methodsA comparative, double-centre, match pair study was performed comparing the data of 44 patients after revisional surgery with 44 patients after primary gastric bypasses, focusing on weight loss, life quality and improvement of co-morbidities. Matching criteria were age, gender, preoperative BMI and follow-up period. Previous procedures consisted of 23 gastric bandings, 13 sleeve resections, 4 LRYGB and 4 vertical banded gastroplasties.
resultsExtra weight loss (EWL) was significantly reduced after revisional gastric bypasses compared to primary intervention (EWL 66 vs. 91 %, p<0.05). Life quality scores were also decreased in the revisional group compared to the control group without statistical significance (SF 36 score 635 vs. 698.5, p=0.22; Moorehead-Aldert II score 1.4 vs. 2.0, p=0.10). The resolution rate of co-morbidities (T2DM, hypertension, gastro-oesophageal reflux (GER), osteoarthrosis, sleep apnoea) was also higher after primary gastric bypasses.
conclusionsRevisional LRYGB is an effective and safe method for patients with inadequate weight loss after previous bariatric surgery concerning weight reduction, life quality and improvement of co-morbidities. Our results indicate lower efficacy of revisional compared to primary LRYGB reaching statistical significance in regard to weight loss.
