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

We have explored the processes regulating presynaptic calcium concentration ([Ca(2+)](i)) in the generation of post-tetanic potentiation (PTP) at crayfish neuromuscular junctions, using spectrophotometric dyes to measure changes in [Ca(2+)](i) and [Na(+)](i) and effects of inhibitors of Ca(2+)-transport processes. The mitochondrial Na(+)/Ca(2+) exchange inhibitor CGP 37157 was without effect, whereas the reverse mode plasmalemmal Na(+)/Ca(2+) exchange inhibitor KB R7943 reduced PTP and Ca(2+) accumulation caused by increased [Na(+)](i). Exchange inhibitory peptide and C28R2 had opposite effects, consistent with their block of the plasma membrane Ca(2+) ATPase. All drugs except CGP 37157 reduced Ca(2+) accumulation caused by Na(+) accumulation, which occurred on block of the Na(+)/K(+) pump, acting in proportion to their effects on plasmalemmal Na(+)/Ca(2+) exchange. We find no role for mitochondrial Na(+)/Ca(2+) exchange in presynaptic Ca(2+) regulation. The plasma membrane Na(+)/Ca(2+) exchanger acts in reverse mode to admit Ca(2+) into nerve terminals during and for some minutes after tetanic stimulation, while at the same time the plasma membrane Ca(2+) ATPase operates as an important Ca(2+) removal process. The interplay of these two Ca(2+) transport processes with Na(+)-independent mitochondrial Ca(2+) fluxes and the plasmalemma Na(+)/K(+) pump determines the magnitude of tetanic [Ca(2+)](i) accumulation and potentiation of excitatory transmission, and the post-tetanic time courses of decay of elevated [Ca(2+)](i) and PTP.
