1 · What the graph read from 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.

2 · The registry

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

purposeWeight loss during post-bariatric surgery period has been linked to both reduced ASCVD mortality and overall mortality. Atherosclerosis causes arteries to lose their elasticity and become more stiff resulting in increased pulse wave velocity (PWV). It has been revealed that PWV favorably predicts subsequent ASCVDs. The goal of this systematic review and meta-analysis was to see how bariatric surgery affected PWV, an index of arterial stiffness. MATERIALS AND

methodsA systematic literature search in four databases was performed. Also, Cochrane guidelines were reviewed to determine bias possibility in the related studies. Comprehensive Meta-Analysis (CMA) V2 software is used to conduct the meta-analysis. Studies were evaluated regarding heterogeneity in design, populations under investigation, and treatment duration using random-effects model and the generic inverse variance weighting approach. A random-effect meta-regression approach was used to investigate the association with the estimated effect size. Evaluation of funnel plot, Egger's weighted regression, and Begg's rank correlation tests were utilized to estimate the presence of publication bias in the meta-analysis.

resultsThe results of meta-analysis on 13 trials including 1426 individuals demonstrated a remarkable decline of PWV after bariatric surgery (WMD: -0.652, 95% CI: -1.004, -0.301, p<0.001). The random-effects meta-regression revealed no evidence of significant correlation between the changes in PWV and initial BMI, BMI changes, or duration of follow-up.

conclusionThe decrease of PWV might be utilized as an independent surrogate marker of improvement of ASCVD risk after bariatric surgery.
