Changes in Body Composition and Biochemical Parameters Following Laparoscopic One Anastomosis Gastric Bypass: 1-Year Follow-Up.
Article in Obesity surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 3 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
BACKGROUND/
aimLittle data is available on body composition and biochemical parameter changes after one anastomosis gastric bypass (OAGB) surgery. This study was therefore conducted to assess body composition and biochemical parameter changes in patients who underwent OAGB. The relationship between the percentage of total weight loss (%TWL) with percentage changes in body composition and biochemical parameters was measured in the first year after surgery. MATERIALS AND
methodsThis retrospective study was carried out on 363 patients (mean age 39.93 ± 9.98 years) who underwent OAGB between January 2011 and November 2018. Anthropometric, body composition and biochemical measurements were recorded before and 1 year after surgery. For paired data, a paired sample t test or Wilcoxon test was used. Spearman or Pearson correlation test was used to evaluate the relationship between % TWL and changes in body composition and biochemical parameters.
resultsThe average %TWL at 1 year following surgery was 35.72 ± 6.85. Fat and muscle tissue and also serum levels of glycemic parameters, low density lipoprotein, triglycerides (TG), total cholesterol, zinc, albumin, hemoglobin, hematocrit, and platelet had decreased a year after OAGB (P < 0.05). The postoperative levels of HDL-c, vitamins D, B12, and folic acid were dramatically higher than the preoperative values. Higher %TWL significantly correlated to greater decreases in body fat, muscle mass, and serum TG at 1 year post-surgery, compared to preoperative values.
conclusionOAGB may be effective over a follow-up period of 1 year in achieving weight, fat mass reduction, and improved serum levels of glycemic parameters and lipid profiles.
