Normal and osteoporotic human osteoblast behaviour after 1,25-dihydroxy-vitamin D(3) stimulation.
Article in Rheumatology international, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
In order to examine the effects of vitamin D on osteoblast function and to evaluate if osteoporotic and normal osteoblasts show a different behaviour in response to vitamin D, this report investigates the changes in osteocalcin production, after 1,25-dihydroxy-vitamin D(3) stimulation of cultured osteoblasts derived from osteoporotic patients. Our results indicate an inadequate osteoblastic function in osteoporosis and demostrate that 1,25-dihydroxy-vitamin D(3) can stimulate the metabolic activity of human osteoblasts in vitro. Considering that osteoporotic bone samples were representative of senile osteoporosis, our results may indicate a different metabolic phenotype in osteoporotic osteoblasts compared with normal osteoblasts. The increased osteocalcin production after 1,25-dihydroxy-vitamin D(3) stimulation of osteoporotic osteoblasts suggests a reduced, but not absent, anabolic function in senile osteoporotic osteoblasts. The results of this study confirm the validity of vitamin D(3) to treat senile osteoporosis and suggest the need of higher vitamin D(3) intake in senile osteoporotic patients than in younger subjects.
