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

Background: Vitamin D deficiency (VDD) is common among women, particularly those with central adiposity. This study examines the predictors of vitamin D levels, focusing on age, adiposity and muscle composition. Methods: A cross-sectional study was conducted with 397 women aged 18-59 years in Jordan. Vitamin D levels were measured using high-performance liquid chromatography. Anthropometric and body composition metrics, including fat-free mass index, conicity index, body mass index (BMI) adjusted skeletal muscle mass index (SMI BMI) and central adiposity measures (waist circumference (WC) and waist-to-hip ratio (WHR)), were analysed. Statistical analyses included χ Results: Age was the strongest predictor of vitamin D levels, with older women exhibiting higher mean concentrations (42.80±11.01 years in the adequate group vs 36.45±11.22 years in the inadequate group; p<0.001). Central adiposity measures were significantly associated with vitamin D adequacy: WC<88 cm (73.8% vs 5.0%, p<0.001) and WHR<0.85 (20.3% vs 9.1%, p=0.001). Generalised adiposity measures, including BMI, were not significant in univariate analysis (p=0.668), but BMI was a negative predictor in Lasso regression (β=-1.078, 95% CI -1.400 to -0.756). SMI BMI showed a borderline negative association (p=0.054). Conclusions: Age and central adiposity are the key predictors of vitamin D levels, emphasising the importance of fat distribution over generalised measures. Public health strategies should target central adiposity and muscle health, especially in younger women at risk of VDD.
