Menopausal bone loss is partially regulated by dietary intake of vitamin D.
Trial report in Calcified tissue international, 1992. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Five years ago we reported results from a cross-sectional study of the effect of nutritional factors on calcium-regulating hormones and bone loss in perimenopausal women. We found an inverse correlation between serum 25-hydroxyvitamin D (25OHD) and immunoreactive parathyroid hormone (PTH), and we postulated that over time, women with lower 25OHD would lose more bone because of increased bone remodeling induced by secondary hyperparathyroidism. We have followed 38 of these women for 5 years. Twenty-two have gone through menopause and we are reporting observations on these 22 subjects. Bone mineral analysis was performed twice a year at the distal and mid-radius using single-photon absorptiometry. The slope of the bone mineral content curve was calculated by least squares. Bone loss increased within 6 months of the rise in serum follicle stimulating hormone (FSH) to greater than 40 mIU/ml. We continued to see a negative correlation between 25OHD and PTH (r = -0.450, P = 0.03). Premenopause, PTH was negatively correlated with the proximal bone mineral content (PBMC) slope (-0.604, P = 0.002). The distal bone mineral content (DBMC) 5-year slope was correlated with dietary vitamin D (r = 0.509, P = 0.02), the higher the intake, the less negative the slope. The 5-year PBMC slope was negatively correlated with serum osteocalcin (OC) levels (r = -0.382, P = 0.08). Before menopause, the change in PBMC was positively correlated with OC (r = 0.450, P = 0.03). Postmenopause, the correlation with DBMC slope was negative (r = -0.506, P = 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
