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.
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
The parameters of coupled respiration and transport of calcium ions in mitochondria isolated from the heart of rats were studied in two modes of exposure to epinephrine for modelling myocardial damage. In 24 h after injection of 1.5 mg/kg epinephrine to rats, we observed a decrease in the efficiency of oxidative phosphorylation in heart mitochondria in the presence of both NADH- and FADH-dependent respiratory substrates. Increasing the epinephrine dose and exposure (2 mg/kg, 72 h) led to a more pronounced decrease in the ADP/O coefficient when succinate was used as a substrate, which indicated a predominant decrease in the activity of complex II of the respiratory chain. The injection of epinephrine in the two modes resulted in a decrease in the rate of calcium entry in rat heart mitochondria, but had no effect on mitochondrial calcium retention capacity, which reflects the resistance of the organelles to the induction of the Са
