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

In the mammalian retina, A17 amacrine cells provide reciprocal inhibitory feedback to rod bipolar cells, thereby shaping the time course of visual signaling in vivo. Previous results have indicated that A17 feedback can be triggered by Ca(2+) influx through Ca(2+)-permeable AMPA receptors and can occur independently of voltage-gated Ca(2+) (Ca(v)) channels, whose presence and functional role in A17 dendrites have not yet been explored. We combined electrophysiology, calcium imaging and immunohistochemistry and found that L-type Ca(v) channels in rat A17 amacrine cells were located at the sites of reciprocal synaptic feedback and that their contribution to GABA release was diminished by large-conductance Ca(2+)-activated potassium (BK) channels, which suppress postsynaptic depolarization in A17s and limit Ca(v) channel activation. We also found that BK channels, by limiting GABA release from A17s, regulate the flow of excitatory synaptic transmission through the rod pathway.
