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

Although Ca2+ release from internal stores has been proposed to be important for the induction of long-term synaptic plasticity, the importance of Ca2+ stores localized in presynaptic terminals remains unclear. Here, we have selectively applied pharmacological antagonists to either the presynaptic or postsynaptic cell in paired whole-cell recordings from hippocampal CA3 pyramidal neurons in slice culture. We demonstrate directly the necessary role of presynaptic, but not postsynaptic, ryanodine-sensitive Ca2+ stores in the induction of NMDA receptor (NMDAR)-dependent long-term depression (LTD). Using two-photon laser scanning microscopy, we further find that release from the ryanodine-sensitive stores during prolonged synaptic stimulation generates a slowly rising Ca2+ signal in the presynaptic terminal that is required for the induction of LTD. Moreover, this form of LTD has a significant presynaptic component of expression because it causes a marked decrease in the rate of release from CA3 neuron presynaptic terminals of FM 1-43, a fluorescent probe of synaptic vesicle cycling. Thus, Ca2+ release from presynaptic ryanodine-sensitive stores is critical in the induction of a presynaptic component of NMDAR-dependent LTD.
