Association Between Vitamin D Level and Z-Score Changes of Bone Density in College-Age Saudi Girls: A Cross-Sectional Study.

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
Objective: Vitamin D (VD) deficiency is a worldwide health problem. VD plays a crucial role in calcium homeostasis, phosphorus metabolism and bone health. Still much remain to understand the effect of VD deficiency on bone mass. This study aimed to evaluate the relationship between VD levels and bone mass density (BMD) among college-age Saudi females. Methods: In a cross-sectional study, 460 females with a median age of 21 years, were enrolled, completed a comprehensive, structured questionnaire which was validated by experienced endocrinologist, a dietician, and a statistician. Body mass indexes (BMI) were calculated, and BMD was estimated through quantitative ultrasound to ankle. Serum VD, calcium, phosphate, parathyroid hormone, and alkaline phosphatase were measured using chemiluminescent immunoassay technique. Results: VD deficiency reached up to 83.3% (66.9% insufficiency and 16.4% deficiency). Lower than normal BMD was detected in 18.3% of subjects, with only 1.1% having a non-age-matched high risk for osteoporosis. The significant independent predictors of Z-score were age of menarche, menstrual irregularities, dairy products consumption, physical activity, BMI, alkaline phosphatase, and history of previous VD supplementation. Conclusion: VD deficiency and low BMD are highly prevalent among college-age Saudi females. Low BMD is not linked to serum level of VD but to its previous use as a supplementation. Early lifestyle changes, attention to gynecological problems, and prevention of VD deficiency are all needed to support BMD among these girls.
