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

Ca(2+) channel beta subunits determine the transport and physiological properties of high voltage-activated Ca(2+) channel complexes. Our analysis of the distribution of the Ca(v)beta subunit family members in hippocampal neurons correlates their synaptic distribution with their involvement in transmitter release. We find that exogenously expressed Ca(v)beta(4b) and Ca(v)beta(2a) subunits distribute in clusters and localize to synapses, whereas Ca(v)beta(1b) and Ca(v)beta(3) are homogenously distributed. According to their localization, Ca(v)beta(2a) and Ca(v)beta(4b) subunits modulate the synaptic plasticity of autaptic hippocampal neurons (i.e., Ca(v)beta(2a) induces depression, whereas Ca(v)beta(4b) induces paired-pulse facilitation [PPF] followed by synaptic depression during longer stimuli trains). The induction of PPF by Ca(v)beta(4b) correlates with a reduction in the release probability and cooperativity of the transmitter release. These results suggest that Ca(v)beta subunits determine the gating properties of the presynaptic Ca(2+) channels within the presynaptic terminal in a subunit-specific manner and may be involved in organization of the Ca(2+) channel relative to the release machinery.
