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 present study was undertaken to evaluate ectopic new bone formation effects of apatite-coated silk fibroin scaffolds (mSS) seeded with adenovirus-mediated bone morphogenic protein-2 gene (AdBMP-2) transduced canine bone marrow stromal cells (bMSCs) in nude mice. In this study, bMSCs derived from canine were cultured and transduced with AdBMP-2 adenovirus-mediated enhanced green fluorescent protein gene (AdEGFP) in vitro. Osteogenic differentiation of bMSCs was determined by alkaline phosphatase (ALP) activity analysis, and the transcript levels for BMP-2, osteopontin (OPN), osteocalcin (OCN) and bone sialoprotein (BSP) genes via real-time quantitative PCR (RT-qPCR) analysis. The ectopic bone formation effects of mSS seeded with AdBMP-2-modified bMSCs were evaluated through histological and histomorphological analysis 4, 8 and 12 weeks post-operation in nude mice. ALP activity was statistically increased in the AdBMP-2 group, when compared with control groups. The mRNA expression of BMP-2, OPN, OCN and BSP was also statistically up-regulated 6 and 9 days after AdBMP-2 transduction. Significantly higher bone volume was achieved in AdBMP-2-transduced bMSCs/mSS constructs than that of AdEGFP-transduced bMSCs/mSS or bMSCs/mSS groups at 4, 8 and 12 weeks (P < 0.01). These results demonstrated that mSS seeded with AdBMP-2-transduced canine bMSCs can promote ectopic new bone formation and maturation in nude mice, suggesting the potential of this silk-scaffold-based tissue-engineered bone for further bone regeneration studies in canine models.
