1 · What the graph read from it

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.

2 · The registry

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

Hepatocytes have been successfully generated from human pluripotent stem cells (hPSCs). However, the cost-effective and clinical-grade generation of hepatocytes from hPSCs still need to be improved. In this study, we reported the production of functional hepatocytes from clinical-grade human embryonic stem cells (hESCs) under good manufacturing practice (GMP) requirements. We sequentially generated primitive streak (PS), definitive endoderm (DE), hepatoblasts and hepatocyte-like cells (HLCs) from hESCs in the different stages with completely defined reagents. During hepatoblast differentiation, dimethyl sulfoxide (DMSO), transferrin, L-ascorbic acid 2-phosphate sesquimagnesium salt hydrate (Vc-Mg), insulin, and sodium selenite were used instead of cytokines and FBS/KOSR. Then, hepatoblasts were differentiated into HLCs that had a typical hepatocyte morphology and possessed characteristics of mature hepatocytes, such as metabolic-related gene expression, albumin secretion, fat accumulation, glycogen storage, and inducible cytochrome P450 activity in vitro. HLCs integrated into the livers of Tet-uPA Rag2
