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
We have previously reported that human neonatal foreskin stromal cells (hNSSCs) promote angiogenesis in vitro and in chick embryo chorioallantoic membrane (CAM) assay in vivo. To examine the in vivo relevance of this observation, we examined in the present study the differentiation potential of hNSSCs in ex vivo organotypic cultures of embryonic chick femurs. Isolated embryonic chick femurs (E10 and E11) were cultured for 10 days together with micro-mass cell pellets of hNSSCs, human umbilical vein endothelial cells (HUVEC) or a combination of the two cell types. Changes in femurs gross morphology and integration of the cells within the femurs were investigated using standard histology and immunohistochemistry. After 10 days, the femurs that were cultured in the presence of hNSSCs alone or hNSSC + HUVEC cells grew longer, exhibited thicker diaphysis and an enlarged epiphyseal region compared to control femurs cultured in the absence of cells. Analysis of cell-femur interactions, revealed intense staining for CD31 and enhanced deposition of collagen rich matrix along the periosteum in femurs cultured with hNSSCs alone or hNSSCs + HUVEC and the most pronounced effects were observed in hNSSC + HUVEC cultures. Our data suggest that organotypic cultures can be employed to test the differentiation potential of stem cells and demonstrate the importance of stem cell interaction with 3D-intact tissue microenvironment for their differentiation.
