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

Spontaneous ongoing synaptic activity is thought to play an instructive role in the maturation of the neuronal circuits. However the type of synaptic activity involved and how this activity is translated into structural and functional changes is not fully understood. Here we show that ongoing glutamatergic synaptic activity triggers a long-lasting potentiation of gamma-aminobutyric acid (GABA) mediated synaptic activity (LLP(GABA-A)) in the developing rat hippocampus. LLP(GABA-A) induction requires (i) the activation of AMPA receptors and L-type voltage-dependent calcium channels, (ii) the release of endogenous brain-derived neurotrophic factor (BDNF), and (iii) the activation of postsynaptic tropomyosin-related kinase receptors B (TrkB). We found that spontaneous glutamatergic activity is required to maintain a high level of native BDNF in the newborn rat hippocampus and that application of exogenous BDNF induced LLP(GABA-A) in the absence of glutamatergic activity. These results suggest that ongoing glutamatergic synaptic activity plays a pivotal role in the functional maturation of hippocampal GABAergic synapses by means of a cascade involving BDNF release and downstream signalling through postsynaptic TrkB receptor activation.
