Unraveling folate deficiency: prevalence, biochemical associations, genetic determinants, and strategies for adolescent health in North India.
Article in European journal of clinical nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundMicronutrient deficiency is a global public health concern, especially among the adolescents of developing countries including India. Folate, an essential B-vitamin plays an indispensable role in various physiological processes throughout life. This is a cross-sectional study to determine prevalence of folate insufficiency among North-Indian school-going adolescents of various socio-economic backgrounds.
methodsA total of 3129 healthy school-going adolescents from North India were selected for the study and circulatory folate levels were measured using an electrochemiluminescence assay. Relationship of circulatory folate with various biochemical and anthropometric parameters were evaluated. Genetic determinants of folate levels in the study population were explored via both genome-wide and exome-wide association studies.
resultsOur results indicate higher prevalence (41%) of folate insufficiency in urban adolescents attending government-funded schools, with distinct relationship of folate levels, biochemical parameters, and anthropometric traits with varied socioeconomic strata. Girls exhibited a higher percentage of folate insufficiency than their male contemporaries. Results from genome-wide association study indicate significant associations of MYO1B (p = 5.13 × 10
conclusionsOur study highlights the importance of large-scale studies on prevalence of folate insufficiency and nutrigenomic regulation of folate levels in Indian population. Implementing multifaceted measures including food fortification, dietary diversification and health education in adolescents is crucial to combat folate deficiency in developing nations like India.
