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
Currently, the supply of beta cells for islet transplantation in the treatment of type 1 diabetes is limited. Enteroendocrine cells (EECs) are believed to have high potential as stem cells because they share significant developmental similarities with beta cells. In a previous study, we derived EEC cells that secrete individual gut hormones from STC-1 cells. This study aimed to examine intestinal hormone secretion and expression, investigate the expression of developmental-related transcription factors, and analyze the effect of MEOX on insulin gene expression in isolated EECs. The expression and secretion of enteroendocrine hormones were evaluated in L6 and K34 cells from STC-1 cells. Expression patterns of beta cell- and development-related genes in L6 and K34 cells were compared with beta cells. Comparisons of the MEOX-induced expression of Ins in beta cells and GLP-1-secreting cells were investigated. Both L6 and K34 cells predominantly expressed Glp1 and Gip, respectively. The secretion pattern of GLP-1 in L6 cells was similar to that of GLUTag cells. Previous microarray analysis confirmed MEOX as developmentally relevant transcription factors expressed in beta cells. Overexpression of MEOX showed a tendency to increase Ins expression in L6 and GLUTag cells, but not in MIN6 cells. However, when PDX1 and MEOX were co-expressed in GLUTag cells, insulin expression was suppressed, similar to that observed in MIN6 cells. These findings suggest a potential role for MEOX in regulating the expression of the Ins gene in both beta cells and GLP-1-secreting cells. Further studies are warranted to elucidate the underlying mechanism.
