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
Despite differences in the phamacokinetics of 25-hydroxycholecalciferol (25(OH)D3) and 25-hydroxyergocalciferol (25(OH)D2) in man, the effects of these and their 1α-hydroxylated forms (1,25(OH)2D3 and 1,25(OH)2D2) on cellular activity of vitamin D-responsive cells have hardly been compared. We studied differences in the effects of these metabolites on cell number, gene transcription, protein expression and mineralisation of cultured human bone marrow-derived stromal cells (hBMSC) and rapidly mineralising mouse 2T3 osteoblasts. 50-1000 nM 25(OH) and 0.05-10 nM 1,25(OH)2 metabolites were used. At high concentrations, 25(OH)D2/D3 and 1,25(OH)2D2/D3 suppressed cell number in both human and mouse cells. The suppression was greater with cholecalciferol (D3) metabolites than with those of ergocalciferol (D2). In both cell types, 25(OH)D2 and 25(OH)D3 increased the expression of osteopontin, osteocalcin, collagen-1, receptor activator of nuclear factor kappa-B ligand, vitamin D receptor, CYP24A1 and CYP27B1 genes. Whereas there was little or no difference between the effects of 25(OH)D2 and 25(OH)D3 in hBMSCs, differences were observed in the magnitude of the effects of these metabolites on the expression of most studied genes in 2T3 cells. Alkaline phosphatase (ALP) activity was increased by 25(OH)D2/D3 and 1,25(OH)2D2/D3 in hBMSC and 2T3 cells, and the increase was greater with the D3 metabolites at high concentrations. In hBMSCs, mineralisation was also increased by 25(OH)D2/D3 and 1,25(OH)2D2/D3 at high concentrations, with D3 metabolites exerting a greater influence. In 2T3 cells, the effects of these compounds on mineralisation were stimulatory at low concentrations and inhibitory when high concentrations were used. The suppression at high concentrations was greater with the D3 metabolites. These findings suggest that there are differences in the effects of 25-hydroxy and 1α,25(OH)2 metabolites of D3 and D2 on human preosteoblasts and mouse osteoblasts, with the D3 metabolites being more potent in suppressing cell number, increasing ALP activity and influencing mineralisation.
