Characteristics of changes in bone mineral density and body composition in obesity patients after metabolic and bariatric surgery: A prospective cohort study.
Article in Diabetes, obesity & metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
aimsTo explore the changes in bone mineral density (BMD) and body composition in patients after bariatric surgery using dual-energy X-ray absorptiometry (DXA) and quantitative computed tomography (QCT), analyse the relationships between these changes and weight loss, and the correlations between the parameters of DXA and QCT. MATERIALS AND
methodsSixty-five patients who underwent surgery between March 2022 and September 2024 were prospectively enrolled. BMD and body composition were measured by DXA and QCT before and after surgery. Laboratory tests were performed.
resultsThe area BMD (aBMD) of lumbar spine (LS) decreased by 3.19 (0.09, 6.50) %, the aBMD of femoral neck decreased by 8.35 (4.66, 12.77) %, the aBMD of total hip decreased by 6.78 (3.98, 10.43) %, and the volumetric BMD (vBMD) of LS decreased by 1.57% ± 8.83%. ΔvBMD was smaller than ΔaBMD-LS (p < 0.05). BMI, fat tissue in the whole body and trunk, and lean soft tissue (LST) all decreased significantly (p < 0.05). The reduction rate of visceral adipose tissue was significantly higher than that of subcutaneous adipose tissue (p < 0.05). There was a weak positive correlation between ΔBMI and ΔaBMD-LS (r = 0.254, p < 0.05), and ΔBMI was positively correlated with the changes in various body compositions (p < 0.05).
conclusionsThe decline of BMI after surgery was accompanied by a decrease in BMD, fat and LST content, with different proportions of decrease. Our findings indicate that QCT can serve as a supplementary method for postoperative follow-up of BMD and body composition in patients undergoing bariatric surgery.
