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
aimsThe objective of this study was to determine the prevalence of vitamin D and calcium supplement use, and association with serum 25-hydroxy-vitamin D(25(OH)D) and demographic and socioeconomic variables in Iranian elderly. SETTINGS AND
designThis cross-sectional study was conducted in health centers of Tehran, capital of Iran.
methodsA total of 600 men and women were recruited using a two-stage cluster sampling method from 60 health centers. Participant's inclusion criteria included enrolling older adults over 60 years old who able to answer questions. We used valid and reliable questionnaires to record dietary intake of vitamin D and calcium. Any dietary supplements which included vitamin D/calcium were recorded. 25(OH)D level was measured. Participants were categorized as supplement users if they had taken supplements during last month.
resultsThe mean age of participants was 67.16 ± 6.07 years. Vitamin D supplements were used more often by females (OR = 11.89, 95% confidence interval (CI): 4.82-29.34), high educated subjects (OR = 3.49, 95% CI: 1.45-8.44), participants who did more physical activities (OR = 2.75, 95% CI: 1.52-5.00), and subjects who took antiosteoporosis medications (OR = 6.90, 95% CI: 2.84‑16.78). Calcium supplements were used more often by females (OR = 13.05, 95% CI: 5.19-32.81), more physical activities participants (OR = 2.17, 95% CI: 1.20-3.92), and antiosteoporosis users (OR = 8.31, 95% CI: 3.43-20.14). Significant positive associations were seen between 25(OH) D levels and osteoporosis (
conclusionIn this population of Tehranian adults, the prevalence of vitamin D and calcium supplement use may be attributed to educational level and underlying disease. Vitamin D supplementation, osteoporosis, and sun exposure were the strong predictors of vitamin D status.
