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 crosstalk between cells is important for differentiation of cells. Murine-derived feeder cells, SNL76/7 feeder cells (SNLs) or mouse primary embryonic fibroblast feeder cells (MEFs) are widely used for culturing undifferentiated human induced pluripotent stem cells (hiPSCs). It is still unclear whether different culture conditions affect the induction efficiency of definitive endoderm (DE) differentiation from hiPSCs. Here we show that the efficiency of DE differentiation from hiPSCs cultured on MEFs was higher than that of hiPSCs cultured on SNLs. The qPCR, immunofluorescent and flow cytometry analyses revealed that the expression levels of mRNA and/or proteins of the DE marker genes, SOX17, FOXA2 and CXCR4, in DE cells differentiated from hiPSCs cultured on MEFs were significantly higher than those cultured on SNLs. Comprehensive RNA sequencing and molecular network analyses showed the alteration of the gene expression and the signal transduction of hiPSCs cultured on SNLs and MEFs. Interestingly, the expression of non-coding hXIST exon 4 was up-regulated in hiPSCs cultured on MEFs, in comparison to that in hiPSCs cultured on SNLs. By qPCR analysis, the mRNA expression of undifferentiated stem cell markers KLF4, KLF5, OCT3/4, SOX2, NANOG, UTF1, and GRB7 were lower, while that of hXIST exon 4, LEFTY1, and LEFTY2 was higher in hiPSCs cultured on MEFs than in those cultured on SNLs. Taken together, our finding indicated that differences in murine-feeder cells used for maintenance of the undifferentiated state alter the expression of pluripotency-related genes in hiPSCs by the signaling pathways and affect DE differentiation from hiPSCs, suggesting that the feeder cells can potentiate hiPSCs for DE differentiation.
