1 · What the graph read from 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.

2 · The registry

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

backgroundData on gastrointestinal (GI) side effects of bariatric surgery are limited because of incomplete reporting, cross-sectional samples, and nonstandardized assessments.

objectiveTo report on GI side effects over the first 6 months after Roux-en-Y gastric bypass (RYGB) and laparoscopic adjustable gastric banding (LAGB).

settingAcademic medical center, United States.

methodsOne hundred forty-four patients completed a standardized clinical interview 6 months after operation, including questions on the occurrence and frequency of episodes of dumping syndrome, vomiting, and plugging for each of the past 6 months; monthly rates were stable, so results were averaged over the entire period. Although data were collected as part of a randomized controlled trial, randomization group and the interaction of group by surgical procedure were not related to GI side effects. Thus, results are reported by procedure only (RYGB, n = 87; LAGB, n = 56).

resultsRYGB patients had a higher preoperative body mass index (BMI) than LAGB patients (46.8±6.8 versus 43.5±4.8 kg/m(2), respectively; P = .001), were more likely to report dumping (45.7% versus 4.7%, P<.0001), and were less likely to report plugging (45.7% versus 79.1%, P = .0005). Vomiting did not differ significantly by procedure (68.6% versus 65.1%, P = .7). Most patients experienced each GI side effect less than once per week.

conclusionAlthough self-reported GI side effects were common over the first 6 months after operation, the frequency of episodes was relatively low. Longer-term follow-up is needed to determine whether symptoms worsen or improve over time.
