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

backgroundSerum vitamin D levels have been linked to the risk of developing type 2 diabetes (T2D), but findings across studies remain inconsistent.

methodsThis study included 9,522 participants with a mean age of 43.55 ± 0.34 years, of whom 52.76% were male, from the 2007-2014 National Health and Nutrition Examination Survey (NHANES) with complete data on serum vitamin D, T2D diagnosis, and relevant covariates. Participants were categorized into three groups based on serum vitamin D levels: sufficient (>75 nmol/L), suboptimal (50-74 nmol/L), and deficient (<50 nmol/L). Restricted cubic spline and multivariable logistic regression models were used to analyze the relationship between serum vitamin D and T2D risk.

resultsAfter adjusting for confounders (sex, ethnicity, age, BMI, education, marital status, physical activity, alcohol consumption, smoking, PIR, and depressive symptoms), participants in the sufficient (OR = 0.68; 95% CI: 0.53-0.87) had significantly lower T2D risk compared to the deficient group (

conclusionsSufficient serum vitamin D levels are associated with a lower risk of T2D, with the optimal level identified as 74.99 nmol/L. Further randomized controlled trials are needed to confirm these findings.
