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

backgroundVitamin B12 deficiency, hyperhomocysteinemia, and diabetes are emerging determinants of cardiovascular risk, particularly among women. Early detection and treatment represent an important public health opportunity to reduce the burden of disease and promote health equity.

objectiveWe aimed to quantify the prevalence of vitamin B12 deficiency, hyperhomocysteinemia, and diabetes, and to evaluate the potential impact of detecting and addressing these conditions on reducing CVD risk in adult Mexican women.

methodsWe analyzed data from 1197 women aged 20-49 years from Mexico's 2022-2023 National Health and Nutrition Survey (ENSANUT). Serum vitamin B12, folate, and homocysteine were quantified, and 10-year CVD risk was estimated using Framingham and Globorisk models. Population-attributable fractions and cost-benefit analyses were used to assess preventable CVD cases and the economic feasibility of nationwide vitamin B12 supplementation.

resultsNationwide, 37.2% of women have vitamin B12 deficiency, and 30.6% have borderline levels. In Southern Mexico, the prevalence of vitamin B12 deficiency is higher, reaching 52.4%. Elevated homocysteine levels were detected in 12.3% of women. The predicted number of preventable CVD cases ranged from 10,000 to 14,000, and the benefit-cost ratio exceeded 1, supporting economic feasibility.

conclusionsVitamin B12 deficiency and hyperhomocysteinemia are very common among Mexican women and are associated with an increased cardiovascular risk, especially in those aged 40 to 49. The analysis showed that implementing a national vitamin B12 supplementation strategy could be a cost-effective preventive measure, with a benefit-cost ratio ranging from 1.93 in the base case to 2.98 when broader societal savings are taken into account. These findings highlight the potential of targeted nutritional interventions to reduce the burden of cardiovascular disease in women.
