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
objectivesVitamin D and B12 deficiency in older adults is associated with osteoporosis and dementia, respectively. The objective of this study is to estimate the prevalence of vitamin D and B12 deficiency among older patients, assess gender-specific differences and analyse seasonal variations in serum levels. MATERIALS AND
methodsThis is a retrospective hospital record-based study. All patients undergoing vitamin D and/or B12 estimation from October 2022 to September 2023 in the Biochemistry laboratory of AIIMS Raebareli, India, were included. Serum vitamin D and B12 assays were performed using chemiluminescence immunoassays on VITROS ECiQ Immunodiagnostic Systems. For vitamin D, ≥30 ng/mL was considered normal, 20-30 ng/mL as insufficient and <20 ng/mL as deficiency. For vitamin B12, ≥300 pg/mL was considered normal, 200-300 pg/mL as borderline and <200 pg/mL as deficiency. Statistical analysis was performed in IBM SPSSv26.
resultsWe estimated the levels of vitamin D in 1 647 older patients and those of vitamin B12 in 2 298 older patients. The prevalence of vitamin D insufficiency (20-30 ng/mL), vitamin D deficiency (<20 ng/mL), borderline B12 (200-300 pg/mL) and B12 deficiency (<200 pg/mL) was seen in 31.9%, 28.9%, 17.1% and 17.1% of subjects, respectively. Female participants had significantly lower vitamin D and higher vitamin B12 levels than male subjects. Significant seasonal variations in levels of vitamins D and B12 were observed, with the lowest levels being detected in March (F=4.98, p=0.00) and August (F=2.51, p=0.04), respectively.
conclusionOlder patients in North India suffer from a high burden of vitamin D and B12 deficiency. Introducing a nutritional supplementation programme for older persons and liberalisation of non-vegetarian food sales may be helpful.
