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

Mitochondria and endoplasmic reticulum (ER) are important modulators of intracellular calcium signaling pathways, but the role of these organelles in shaping synaptic calcium transients in dendrites of pyramidal neurons remains speculative. We have measured directly the concentrations of total Ca (bound plus free) within intracellular compartments of proximal dendrites of CA3 hippocampal neurons at times after synaptic stimulation corresponding to the peak of the cytoplasmic free Ca2+ transient (1 sec), to just after its decay (30 sec), and to well after its return to prestimulus levels (180 sec). Electron probe microanalysis of cryosections from rapidly frozen slice cultures has revealed that afferent mossy fiber stimulation evokes large, rapid elevations in the concentration of total mitochondrial Ca ([Ca](mito)) in depolarized dendrites. A single tetanus (50 Hz/1 sec) elevated [Ca](mito) more than fivefold above characteristically low basal levels within 1 sec of stimulation and >10-fold by 30 sec after stimulation. This strong Ca accumulation was reversible, because [Ca](mito) had recovered by 180 sec after the tetanus. Ca sequestered within mitochondria was localized to small inclusions that were distributed heterogeneously within, and probably among, individual mitochondria. By 30 sec after stimulation an active subpopulation of ER cisterns had accumulated more Ca than had mitochondria despite a approximately 1 sec delay before the onset of accumulation. Active ER cisterns retained their Ca load much longer (>3 min) than mitochondria. The complementary time courses of mitochondrial versus ER Ca2+ uptake and release suggest that these organelles participate in a choreographed interplay, each shaping dendritic Ca2+ signals within characteristic regimes of cytosolic Ca2+ concentration and time.
