The Effect of Dumping on Weight Loss in Conversion of Failed Restrictive Surgery: a Cross-Sectional Pilot Study.
Article in Obesity surgery, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeDumping is currently seen as a negative side effect of Roux-en-Y gastric bypass (RYGB). However, it may help patients to comply with their prescribed diet. In this study, we assess the role of dumping on weight loss in patients who have undergone conversion of failed restrictive surgery into RYGB.
methodsAn analysis was performed of 100 consecutive patients who underwent revisional RYGB (rRYGB) between 2006 and 2011 due to inadequate weight loss or band intolerance after laparoscopic adjustable gastric banding (LAGB). The percentage of excess weight loss (%EWL) was used to evaluate weight reduction. The Sigstad clinical diagnostic index was used to detect dumping symptoms.
resultsFifty-five patients (59.1%) suffered from dumping. Overall, dumpers showed a greater %EWL than non-dumpers (83.8 ± 48.0 vs 66.9 ± 44.1%, respectively, p = 0.0725). When rRYGB was performed because of inadequate weight loss following LAGB, dumping played a crucial role in weight loss (88.0 ± 21.2 vs 68.9 ± 34.5%, p = 0.0137). This effect positively correlates to post-LAGB body mass index (BMI) with a statistically significant result at BMI > 35 kg/m
conclusionsThis study provides new insights into the effect of dumping on weight loss in patients who underwent conversion of failed restrictive surgery into RYGB. Based on the findings in our patient group, we suggest that dumping helps patients achieve sustainable weight loss. Therefore, dumping can be regarded as a positive side effect rather than a complication.
