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

backgroundRoux-en-Y gastric bypass (RYGB) is the criterion standard operation for weight loss. Low socioeconomic status (SES) is common in the Veteran population undergoing bariatric surgery, but the impact of SES on long-term weight-loss outcomes is not known. We hypothesize that low socioeconomic status is associated with less weight loss after gastric bypass in long-term follow-up.

methodsWe performed a retrospective review of patients undergoing RYGB at a single Veterans Affairs (VA) hospital. Patients with at least 10 years of follow-up data in the electronic health record were included in the analysis. Weight loss was measured as percent excess body mass index loss (%EBMIL). The primary predictor variable, median household income, was determined using zip codes of patient residences matched to publicly available 2010 U.S. census data. Univariate relationships between income, weight loss, and other patient characteristics were evaluated. We calculated a multivariate generalized linear model of %EBMIL to estimate independent relationships with median household income quartile while controlling for patients' age, race, sex, and VA distance.

resultsComplete 10-year follow-up data were available for 83 of 92 patients (90.2%) who underwent RYGB between 2001 and 2007 and survived at least 10 years. The majority of patients were male (79.5%) and white (73.5%). The mean 10-year %EBMIL was 57.8% (SD: 29.5%, range - 36.0% - 132.8%). In univariate analysis, income was significantly associated with race (p < 0.001) and median distance to the VA bariatric center (p = 0.034), but income did not differ by gender (p = 0.73) or age (p = 0.45). Multivariate analysis revealed significantly lower 10-year %EBMIL for patients with the lowest income compared to patients with low-mid income (p = 0.03) and mid-high income (p = 0.01), after controlling for gender, race, age, and VA distance.

conclusionsLow socioeconomic status is associated with lower weight-loss outcomes, 10 years after RYGB. Durable weight loss is observed in all income groups.
