Changes in 25-Hydroxyvitamin D3 to oral treatment with vitamin D3 in postmenopausal females with osteoporosis.

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
summaryThis study reports on oral treatment with different doses of vitamin D3 ranging from 25 to 200 microg in females with 25-hydroxyvitamin D3 levels < 60 nmol/L screened for participation in an osteoporosis trial. A guidance to safely and efficiently achieve 25-hydroxyvitamin D3 levels > 60 nmol/L is presented.
introductionThe importance of vitamin D for skeletal health has been implemented in clinical trials in osteoporosis. The threshold of 25-hydroxyvitamin D for inclusion has changed from 30 to 60 nmol/L. This study reports on oral treatment with different doses of vitamin D3 in females with 25-hydroxyvitamin D3 levels < 60 nmol/L.
methodsIn 131 postmenopausal females screened for participation in an osteoporosis trial, the 25-hydroxyvitamin D3 concentration was < 60 nmol/L. They were treated with 25 (n = 22), 50 (n = 19), 75 (n = 19), 100 (n = 41) or 200 microg (n = 30) of vitamin D3 daily for at least 10 days.
resultsIn the females treated with 25, 50, 75, 100 and 200 microg of vitamin D3 daily the 25-hydroxyvitamin D3 concentrations increased significantly from 32.4 +/- 2.7 (mean +/- SEM) to 50.8 +/- 2.9, from 46.7 +/- 2.8 to 65.8 +/- 2.6, from 41.6 +/- 2.7 to 67.4 +/- 2.9, from 46.7 +/- 1.4 to 64.4 +/- 2.2 and from 42.1 +/- 2.0 to 71.2 +/- 2.8 nmol/L, respectively (p < 0.001). S-calcium increased significantly but within the reference range (p < 0.006).
conclusionOral vitamin D3 safely increased 25-hydroxyvitamin D3 concentrations in all females above 60 nmol/L. This study demonstrates how to achieve the new recommended 25-hydroxyvitamin D concentrations within the screening period of a clinical trial.
