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

backgroundAbdominal Aortic Calcification (AAC) is closely associated with visceral adiposity. The authors aimed to investigate the relationship between a Body Shape Index (ABSI) and AAC.

methodsData were obtained from the 2013‒2014 cycle of the National Health and Nutrition Examination Survey (NHANES). Weighted multivariable regression, tests for trends, subgroup analysis, and smooth curves were used to explore the association between ABSI and AAC scores, as well as Severe Abdominal Aortic Calcification (SAAC). Receiver Operating Characteristic (ROC) curves were plotted to compare the predictive abilities of ABSI, Weight-adjusted Waist Index (WWI), Body Mass Index (BMI), Waist-to-Height Ratio (WHtR), and Waist Circumference (WC) for AAC and SAAC.

resultsA total of 2741 individuals were included in the present study. The weighted incidence of AAC was 29.12%, and SAAC was 7.94%. After fully adjusting for covariates, each one-unit increase in ABSI was associated with a 0.42-point increase in the AAC score (95% CI: 0.29, 0.63), and the risk of SAAC increased by 37% (95% CI: 1.12, 1.77). Smooth curves showed a nonlinear positive correlation between ABSI and AAC scores, as well as SAAC. No dependence was observed in the subgroup analysis. ROC analysis showed that ABSI was a stronger predictor than WWI, BMI, WHtR, and WC.

conclusionsABSI has a positive correlation with AAC scores and SAAC. However, prospective studies are required to validate the present results.
