Factors Influencing Serum-Hydroxivitamin D Levels and Other Bone Metabolism Parameters in Healthy Older Women.
Article in The journal of nutrition, health & aging, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectiveOlder women have frequently low serum 25-hydroxivitamin D (25[OH]D) concentrations, high parathormone (PTH) levels and low bone mineral density (BMD) values. Endogenous synthesis, dietary habits, sunlight exposure and fat-mass-mediated storage may influence 25(OH)D levels and bone metabolism, but the relevance of these factors in the elderly has yet to be fully elucidated. We aimed to investigate the influence of dietary vitamin D intake and fat mass on serum 25(OH)D levels and bone metabolism in older women.
designCross-sectional.
settingCommunity.
participants218 fit older women attending a biweekly mild fitness program. MEASUREMENTS: Dietary habits was investigated through a 3-day record questionnaire. Serum 25(OH)D and intact parathormone (PTH) concentrations were measured by radioimmunoassay and by a 2-step immunoradiometric assay, respectively. BMD and body composition were estimated using dual-energy X-ray absorptiometry with fan-beam technology.
resultsOnly fat mass showed a significant negative association with 25(OH)D (β=-3.76, p<0.001), and positive associations with whole body, lumbar, femoral neck and total hip BMD. Binary logistic analysis revealed a protective effect of adiposity on secondary hyperparathyroidism (OR=0.42, 95%CI:0.19-0.92, p=0.03). Dietary vitamin D intake was not associated to any of these outcomes.
conclusionFat mass has a greater influence on serum 25(OH)D than dietary vitamin D intake.
