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

Sprouty (Spry) genes encode negative regulators of receptor tyrosine kinase (RTK) signaling, which plays important roles in human embryonic stem cells (hESCs). SPRY2 and SPRY4 are the two most highly expressed Sprouty family members in hESCs, suggesting that they may influence self-renewal. To test this hypothesis, we performed siRNA-mediated knock down (KD) studies. SPRY2 KD resulted in increased cell death and decreased proliferation, whereas SPRY4 KD enhanced survival. In both cases, after KD the cells were able to differentiate into cells of the three germ layers, although after SPRY2 KD there was a tendency toward increased ectodermal differentiation. SPRY2 KD cells displayed impaired mitochondrial fusion and cell membrane damage, explaining in part the increased cell death. These data indicate that Sprouty genes regulate pathways involved in proliferation and cell death in hESCs.
