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

Apoptosis induced by K+/serum deprivation (low K+) in cerebellar granule neurons has been extensively investigated. The mitochondria play a key role in apoptosis by releasing proapoptotic factors into the cytoplasm, and mitochondrial dysfunction has been proposed as an early or initiating event in this model. To directly test this hypothesis, cellular and mitochondrial bioenergetics were quantified by determining the respiratory parameters of coverslip-attached neurons. While oxidative phosphorylation rate decreased 39-49% in low K+, this was due to decreased cellular ATP demand rather than impaired ATP/ADP exchange or respiratory chain inhibition. From 3 to 5 h in low K+, apoptosis progressed from 13 to 40% despite no appreciable change in respiratory parameters. Changes in steady-state O2-, assessed with dihydroethidium, were seen in granule but not hippocampal neurons. The O2- change correlated with changes in [Ca2+]c, but not mitochondrial respiration. Thus, early mitochondrial dysfunction can be excluded in this common model of neuronal apoptosis.
