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

backgroundFibroblast growth factor (FGF) signaling controls self-renewal of neural stem cells during embryonic telencephalic development. FGF receptor 2 (FGFR2) has a significant role in the production of cortical neurons during embryogenesis, but its role in the hippocampus during development and in adulthood has not been described.

methodsHere we dissociate the role of FGFR2 in the hippocampus during development and during adulthood with the use of embryonic knockout and inducible knockout mice.

resultsEmbryonic knockout of FGFR2 causes a reduction of hippocampal volume and impairment in adult spatial memory in mice. Spatial reference memory, as assessed by performance on the water maze probe trial, was correlated with reduced hippocampal parvalbumin+ cells, whereas short-term learning was correlated with reduction in immature neurons in the dentate gyrus. Furthermore, short-term learning and newly generated neurons in the dentate gyrus were deficient even when FGFR2 was lacking only in adulthood.

conclusionsTaken together, these findings support a dual role for FGFR2 in hippocampal short-term learning and long-term reference memory, which appear to depend on the abundance of two separate cellular components, parvalbumin interneurons and newly generated granule cells in the hippocampus.
