Metabolic and bariatric surgery reduces aging biomarkers in patients with obesity, independently of achieving optimal total weight loss.

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
introductionObesity, a chronic disease linked to premature aging, is increasingly managed through metabolic and bariatric surgery (MBS).
aimThis study aimed to evaluate whether changes in biological age markers depended on the optimal weight loss rates resulting from MBS. MATERIALS AND
methodsIn this prospective, observational study, 100 patients with obesity scheduled for MBS from July 2020 to May 2021 underwent a 24-month postoperative follow-up. The telomere length (TL) was assessed using quantitative polymerase chain reaction. We also evaluated DNA damage, C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor α (TNF-α) levels, total oxidant status (TOS), and the metabolic age. We checked whether the percentage of total body weight loss (%TWL) and the percentage excess weight loss (%EWL) correlated with the changes in aging markers postsurgery.
resultsForty patients completed follow-up, with 22 achieving optimal (%TWL ≥20%; %EWL ≥50%) and 18 suboptimal (%TWL <20%; %EWL <50%) surgical outcomes. Both groups showed a significant TL increase and a reduction of DNA damage, CRP, IL-6, and TNF-α levels, TOS, and the metabolic age. A greater change, however, was only observed for the metabolic age in the optimal outcome group. The Δ of change in the other aging markers did not differ between the groups.
conclusionsImprovements in aging markers, such as TL, DNA damage, inflammatory parameters, and TOS occur independently of weight loss rates after MBS, suggesting that weight loss indices alone do not fully capture the therapeutic success of the procedure.
