Do calcium supplements increase serum and urine calcium levels in post-menopausal women?
Observational study in The journal of nutrition, health & aging, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
objectivesThe frequent prescription of calcium supplements with vitamin D by health practitioners is a topic of concern globally. The present study was designed to find out whether the calcium supplements with vitamin D really affect serum and urinary calcium levels in post-menopausal women. DESIGN, SETTINGS AND
participantsThe age-matched comparative study was performed among postmenopausal women who were already on and those who were not on calcium supplements with vitamin D for a period of time in relation to the estimation of the serum calcium and the urine calcium levels. Sixty healthy postmenopausal women were enrolled, with thirty among them forming the study group (SG) - who were on calcium supplements with vitamin D for a period of a month, three months, and up to twelve months - were studied and compared the results obtained with the age-matched control group (CG) of thirty post-menopausal women who were not on calcium supplements. MEASUREMENTS: The serum and the urinary calcium levels were estimated by using appropriate biochemical methods and the data were analysed using relevant statistical methods.
resultsThe serum calcium levels did not vary significantly in SG in spite of consuming calcium supplements over a period of time, whereas the urinary calcium levels increased progressively (p value < 0.005) in those who have taken calcium supplements for a year compared to those who have taken for a month.
conclusionThus, the calcium supplements were of little significance on the serum calcium levels, but have a significant effect on the urinary calcium levels in post-menopausal women.
