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

Phenelzine (PZ) is a scavenger of the lipid peroxidation (LP)-derived reactive aldehyde 4-hydroxynonenal (4-HNE) due to its hydrazine functional group, which can covalently react with 4-HNE. In this study, we first examined the ability of PZ to prevent the respiratory depressant effects of 4-HNE on normal isolated brain cortical mitochondria. Second, in rats subjected to controlled cortical impact traumatic brain injury (CCI-TBI), we evaluated PZ (10 mg/kg subcutaneously at 15 minutes after CCI-TBI) to attenuate 3-hour post-TBI mitochondrial respiratory dysfunction, and in separate animals, to improve cortical tissue sparing at 14 days. While 4-HNE exposure inhibited mitochondrial complex I and II respiration in a concentration-dependent manner, pretreatment with equimolar concentrations of PZ antagonized these effects. Western blot analysis demonstrated a PZ decrease in 4-HNE in mitochondrial proteins. Mitochondria isolated from peri-contusional brain tissue of CCI-TBI rats treated with vehicle at 15 minutes after injury showed a 37% decrease in the respiratory control ratio (RCR) relative to noninjured mitochondria. In PZ-treated rats, RCR suppression was prevented (P<0.05 versus vehicle). In another cohort, PZ administration increased spared cortical tissue from 86% to 97% (P<0.03). These results suggest that PZ's neuroprotective effect is due to mitochondrial protection by scavenging of LP-derived 4-HNE.
