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
The secretion of osteocalcin (OCN) is an excellent differentiation marker for the osteogenic differentiation. This study investigated the secretion of OCN during the osteogenic differentiation of DFCs. During the differentiation of DFCs the extracellular concentrations of OCN were higher in standard cell culture medium than in osteogenic differentiation medium. However, after 4 weeks in the osteogenic differentiation medium the extracellular OCN concentration decreased strongly, whereas the concentration remains high in the control medium. At this point in time DFCs formed connective tissue like structures with mineralized clusters and OCN. Real-time RT-PCR analyses and western-blot analyses proved that OCN was expressed in both cell culture media. However, the expression of the mRNA was inhibited in the osteogenic differentiation medium. These results suggest that DFCs secrete constitutively OCN into the cell culture medium and that the osteogenic differentiation medium suppresses the gene expression of OCN. Moreover, OCN imbeds into the extracellular matrix after the formation of connective tissue like structures, and the soluble OCN in the cell culture medium disappears. Hence, extracellular OCN in the cell culture medium is not a marker for the osteogenic differentiation of DFCs.
