Effects of Roux-en-Y gastric bypass surgery on visceral and subcutaneous fat density by computed tomography.
Article in Obesity surgery, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02091323 (Effect of Modified Laparoscopic Roux-en-Y Gastric Bypass Surgery on Type 2 Diabetics With Lower Body Mass Index in China), which is not on this map. Cited by 18 papers, 1 of them a synthesis 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.

Abstract
We aimed to test the hypothesis that noninvasive fat density by computed tomography (CT) increases after Roux-en-Y gastric bypass (RYGB) and correlates with improved cardiometabolic risk. We examined 21 obese adults before and 12 months after RYGB and 16 obese nonsurgical controls followed for 12 months. Visceral (VAT) and subcutaneous adipose tissue (SAT) density increased after RYGB (P < 0.0001) while remaining stable in controls (P ≥ 0.1). In RYGB subjects, 12-month increase in VAT density correlated with decreased C-reactive protein (CRP) independent of change in VAT area or BMI (both P < 0.05). Twelve-month increase in SAT density correlated with increased HDL cholesterol independent of change in SAT area (P = 0.048), BMI (P = 0.03), or statin use (P = 0.002), and 1 unit increase in SAT density had increased odds of higher total abdominal fat loss (P = 0.002).
