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

During the development of an organism, cells are exposed to a myriad of signals, structural components and scaffolds, which collectively make up the cellular microenvironment. The majority of current developmental biology studies examine the effect of individual or small subsets of molecules and parameters on cellular behavior, and they consequently fail to explore the complexity of factors to which cells are exposed. Here we describe a technology, referred to as arrayed cellular microenvironments (ACMEs), that allows for a high-throughput examination of the effects of multiple extracellular components in a combinatorial manner on any cell type of interest. We will specifically focus on the application of this technology to human pluripotent stem cells (hPSCs), a population of cells with tremendous therapeutic potential, and one for which growth and differentiation conditions are poorly characterized and far from defined and optimized. A standard ACME screen uses the technologies previously applied to the manufacture and analysis of DNA microarrays, requires standard cell-culture facilities and can be performed from beginning to end within 5-10 days.
