Research on DXA bone density measurements and trabecular bone scores in Chinese men and women with obesity before and after bariatric surgery.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveDual energy X-ray absorptiometry (DXA) was used to analyze body composition, bone mineral density (BMD) parameters and the trabecular bone score (TBS) in patients with obesity before, 3 months after and 1 year after bariatric surgery as a method to evaluate the changes in BMD and skeletal microarchitecture (MA) in patients with obesity after bariatric surgery and to provide a basis for further accurate assessment of the bone health status of this population and subsequent treatment.
methodsThis study was a retrospective analysis of 41 patients that underwent DXA imaging before, 3 months after and maximum 1 year after bariatric surgery. The follow-up rate in both periods was 100%. First, the changes in BMD and TBS before and after surgery were compared between patients grouped by sex and obesity degree. Secondly, the correlations between the TBS or BMD and body composition 1 year after surgery were analyzed.
resultsThe BMD and TBS were within the normal range after bariatric surgery. Changes in the BMD and TBS were related to time, the degree of obesity and sex. Changes in the TBS were closely related to changes in the BMD, and the trends in the changes in the BMD were basically the same among the different groups of individuals with obesity of different sexes. A negative correlation was observed between the TBS and fat percentage (total body, leg, trunk, android area), as well as the lumbar spine Z-score in patients 1 year after bariatric surgery (p < 0.05).
conclusionsBariatric surgery in patients with obesity has no obvious adverse effects on BMD or TBS. DXA can be used to better evaluate the changes in BMD and MA in patients with obesity after bariatric surgery, providing a basis for the clinical evaluation of post-bariatric surgery efficacy in these individuals and subsequent accurate assessment of the bone health status and treatment of this population.
