Vitamin D deficiency, bone turnover markers and causative factors among adolescents: a cross-sectional study.
Article in Journal of diabetes and metabolic disorders, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers.
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
backgroundThis cross-sectional population-based study was conducted to elucidate the prevalence of vitamin D deficiency, bone turnover marker's variation and its influencing factors among adolescents of Tehran.
methodsTotally 444 middle and high school (53.6 % in high school) students (both girls and boys) were recruited. A short food frequency questionnaire designed to estimate dietary calcium and vitamin D consumption. Serum levels of calcium, phosphorus, parathyroid hormone (PTH), bone specific alkaline phosphates, 25 (OH) vitamin D, osteocalcin, cross-linked C-telopeptide (CTX), total protein, albumin and creatinine were determined.
resultsVitamin D deficiency was prevalent in adolescents and only 22.4 % of students had normal serum vitamin D. Results revealed that vitamin D insufficiency reported in 34.2 % of students and vitamin D deficiency was in 43.3 % of them. Serum vitamin D, osteocalcin, CTX and bone specific alkaline phosphates were significantly higher in boys in all different ages. Serum levels of 25 (OH) vitamin D had positive influences on bone turnover markers and had negative correlation with PTH.
conclusionsVitamin D deficiency and insufficiency is common among healthy adolescents of Tehran. There is a pressing need to improve vitamin D status among adolescents. Increasing vitamin D fortification of dairy products can be considered as a population-wide public health strategy in Iran.
