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
objectiveTo investigate the effect of silk fibroin-poly-
methodsADSCs were extracted from adipose tissue donated voluntarily by patients undergoing liposuction by enzymatic digestion. The 3rd generation ADSCs were inoculated on CultiSpher G and SF-PLLA microcarriers (set up as groups A and B, respectively), and cultured in the rotary cell culture system. ADSCs cultured in normal two-dimensional plane were used as the control group (group C). Scanning electron microscope was used to observe the microcarriers structure and cell growth. Live/Dead staining and confocal fluorescence microscope was used to observe the distribution and survival condition of cells on two microcarriers. DNA quantification was used to assess cell proliferation on two microcarriers. Real-time fluorescence quantitative PCR (qRT-PCR) was used to detect chondrogenesis, osteogenesis, and adipogenesis related gene expression of ADSCs in 3 groups cultured for 18 days. Flow cytometry was used to identify the MSCs surface markers of ADSCs in 3 groups cultured for 18 days, and differential experiments were made to identify differentiation ability of the harvested cells.
resultsADSCs could be adhered to and efficiently amplified on the two microcarriers. After 18 days of cultivation, the total increment of ADSCs of the two microcarriers were similar (
conclusionThe ADSCs can be amplified by SF-PLLA microcarriers, and the chondrogenic differential ability of harvested cells was up-regulated while the adipogenic differential was down-regulated.
