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
Prior to gastrulation, the Wnt signaling pathway through stabilized β-catenin enhances the differentiation of mouse ES cell into cardiomyocytes. We have recently shown that cardiomyocyte differentiation is enhanced by eosinophil cationic protein (ECP) through accelerated expression of marker genes of early cardiac differentiation. Furthermore, ECP enhanced the expression of Wnt3a in P19CL6 cells which were stimulated to differentiate into cardiomyocytes by DMSO. Following these findings, we evaluated in this study the potential of ECP to activate the Wnt/β-catenin signaling pathway during cardiomyocyte differentiation. Analysis by real time qPCR revealed that ECP increased the expression of Frizzled genes such as Frizzled-1, -2, -4 and -10 in P19CL6 cells in the presence of DMSO. The increased expression of those Wnt receptors was found to inhibit the phosphorylation of β-catenin resulting in the stabilization and translocation of β-catenin into the nucleus of P19CL6 cells during the early stages of cardiomyocyte differentiation. When assessed for β-catenin/TCF transcriptional activity with a TCF-luciferase (TOP/FOP) assay, ECP enhanced luciferase activity in P19CL6 cells during 48 h after transfection with TOP/FOP flash reporter in a stoichiometric manner. Collectively, this suggests that ECP can activate a canonical Wnt/β-catenin signaling pathway by enhancing the stabilization of β-catenin during cardiomyocyte differentiation.
