Comparison of myocardial ischemic/hypoxic staining techniques for evaluating the alleviation of exhaustive exercise-induced myocardial injury by exercise preconditioning.

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
Exercise preconditioning (EP) can alleviate myocardial ischemic/hypoxic injury by inducing endogenous cardioprotection. Hematoxylin-eosin (HE), hematoxylin-basic fuchsin-picric acid (HBFP), and chromotrope-2R brilliant green (C-2R BG) staining have been used to visualize myocardial ischemic/hypoxic changes in previous EP studies, but comprehensive evaluation and comparisons of these methods are lacking. This study evaluated ischemic/hypoxic changes in adjacent myocardial sections by HE, HBFP, and C-2R BG and compared the characteristics of sections stained by these three methods to show changes associated with exercise-induced myocardial ischemic/hypoxic injury. Rats were randomly divided into four groups: control (C), exercise preconditioning (EP), exhaustive exercise (EE), and exercise preconditioning + exhaustive exercise (EP + EE). Adjacent myocardial sections were stained as described above and compared to evaluate the effects of exercise-induced myocardial ischemic/hypoxic injury. The three staining methods revealed consistent localization patterns of myocardial ischemic/hypoxic injury in all groups. Results suggest that EP can alleviate exhaustive exercise-induced myocardial ischemic/hypoxic injury, and the three staining methods are suitable for the histological study of exercise-induced myocardial ischemic/hypoxic injury and protection. HE staining is a simple procedure but is not specific for myocardial ischemic/hypoxic injury. HBFP and C-2R BG staining can be used to specifically visualize myocardial ischemic/hypoxic injury.
