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
backgroundAdolescent mental health disorders represent a growing concern in India, with potential links to nutritional factors remaining underexplored.
objectiveThis pilot study aimed to investigate the association between micronutrient deficiencies (vitamin B12, ferritin, folate, vitamin D, and calcium) and psychosocial impairment (defined as Youth Pediatric Symptom Checklist (Y-PSC) score ≥30) among Indian adolescents attending a tertiary care hospital in Delhi.
methodsA cross-sectional analytical study was conducted over six months at a tertiary care hospital in Delhi. A total of 96 adolescents aged 11-18 years were enrolled through consecutive sampling. Psychosocial functioning was assessed using the Y-PSC, with scores ≥30 indicating impairment. Venous blood samples were analyzed for hemoglobin, serum ferritin, vitamin B12, folic acid, 25-hydroxyvitamin D, and total calcium levels.
resultsPsychosocial impairment was found in 15.6% (15/96) of participants. Adolescents with psychosocial impairment (n=15) had significantly lower mean serum vitamin B12 levels (191.86±63.00 pg/mL) compared to those without impairment (291.09±207.02 pg/mL), with P=0.039 for vitamin B12. Median serum ferritin levels were significantly lower in the impaired group (28.50 ng/mL, IQR: 21.00-42.00) compared to the non-impaired group (45.00 ng/mL, IQR: 24.00-78.00; Mann-Whitney U test, P=0.041). Vitamin B12 deficiency was present in 80% (12/15) of adolescents with psychosocial impairment versus 23.4% (19/81) in those without impairment (P<0.001). In unadjusted analyses, both vitamin B12 deficiency (OR=13.11; 95% CI: 3.35-51.28; P<0.001) and lower ferritin levels were significantly associated with psychosocial impairment. Multivariable logistic regression analysis identified vitamin B12 as significantly associated with psychosocial impairment (OR=0.985; 95% CI: 0.972-0.997; P=0.017), while the association with ferritin did not reach statistical significance in the adjusted model (OR=0.976; 95% CI: 0.948-1.004; P=0.098).
conclusionsPreliminary associations were observed between psychosocial impairment and deficiencies in vitamin B12 and ferritin among Indian adolescents in this pilot study. While causality cannot be established from this cross-sectional design, these findings suggest the potential value of incorporating micronutrient screening into routine psychosocial assessments and warrant further investigation in larger, adequately powered prospective studies.
