Predictors of long-term success after laparoscopic Roux-en-Y gastric bypass in African-American women.
Article in Surgery for obesity and related diseases : official journal of the American Society for Bariatric Surgery, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundLaparoscopic Roux-en-Y gastric bypass (LRYGB) provides sustained weight loss. However, short-term studies have suggested that African Americans (AAs) are not as successful as Caucasians (CAs) after LRYGB.
objectiveThe present study was designed to test the hypothesis that at longer term follow-up AAs are just as successful as CAs after LRYGB.
settingUniversity hospital, United States.
methodsA nested case-control study designed to examine the effect of race as covariate in the long-term success of women undergoing LRYGB. The study matched 3 controls per case subject, and the final numbers for analyses were 78 case patients (AA) and 204 control patients (CA). Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using conditional logistic regression analysis.
resultsThe 2 cohorts (N = 282) were well matched for age (AA 40.3±9.1 years versus CA 41.1±8.9 years), preoperative body mass index (AA 50.6±7.5 kg/m(2) versus CA 50.2±7.1 kg/m(2)), prevalence of type 2 diabetes (T2D) (AA 20.5% versus CA 21.1%), hypertension (AA 69.1% versus CA 52%), and sleep apnea (AA 35.9% versus CA 34.8%). In the AA group, the long-term curve for percentage of excess weight loss (EWL) was significantly (P<.001) lower than the CA group at any time-point. In the present model, diagnosis of T2D in the AA group (OR = 6.1 E8) significantly (P = .002) predicted adequate EWL at 3 years, after controlling for relevant confounders.
conclusionRace significantly affected the long-term EWL at 3 years for patients undergoing LRYGB at the authors' institution. Future research should be directed at determining potential genetic reasons for these differences, including genes associated with T2D.
