Do Complications Alter Postoperative Weight Loss 1 Year After Primary and Revisional Roux-en-Y Gastric Bypass?
Article in Obesity surgery, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 2 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.
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
backgroundAround 10 % of the bariatric surgery patients experience postoperative complications (<30 days). It could be hypothesized that complications influence postoperative weight loss, which is one of the most important endpoints of bariatric surgery. Therefore, this study inventoried the effect of complications on postoperative weight loss.
methodsA consecutive database including patients who were operated from November 2007 onwards was retrospectively reviewed. All short-term complications were classified according to the Clavien-Dindo classification. Weight loss was assessed at 6 and 12 months postoperatively.
resultsA total of 1130 patients underwent either primary (n = 907, 80.3 %) or revisional (n = 233, 19.7 %) surgery till October 2013. Short-term complications occurred in 115 (10.2 %) patients, of whom 48 (41.7 %) had a severe (Clavien-Dindo ≥ 3) complication. One year post surgery, 184 patients (16.3 %) were lost to follow-up. Patients with a short-term complication had a higher percentage of excess weight loss (%EWL) at 6 months (58.6 (SD 16.6) versus 52.9 (SD 17.6), p = 0.003) and 1 year (71.9 (SD 22.3) versus 65.9 (SD 21.3), p = 0.017) of follow-up. Although a trend was seen toward higher BMI loss and total weight loss (TWL) after 6 months, no effect was seen 1 year postoperatively. In multivariable linear regression analysis, complications were not a significant predictor for 1-year %EWL.
conclusionsAlthough short-term complications alter 1-year %EWL, no effect was seen on BMI loss and TWL. In addition, complications were not a predictor in a multivariable linear regression model for 1-year %EWL. It can be concluded that short-term complications do not impair weight loss after Roux-en-Y gastric bypass.
