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

Biological sex affects cardiac tolerance to ischemia and reperfusion, but little is known about sex differences in heart transplantation with donation after circulatory death (DCD). Using a rat model, we characterized differences between sexes both in the donor, during simulated DCD, and in the procured heart, to evaluate recovery upon reperfusion. Adult male, female and ovariectomized Wistar rats underwent simulated DCD with 22 min of warm, in-situ ischemia. Hearts were then explanted and maintained in cold static storage for 30 min. Isolated hearts then underwent normothermic, oxygenated reperfusion for 60 min with left ventricular loading. In-situ characteristics, as well as ventricular function, coronary flows and metabolic post-ischemic recovery were assessed. Post-ischemic ventricular recovery was significantly higher in female compared to male and ovariectomized hearts. Furthermore, several in-situ circulating factors, including free fatty acids and potassium, were significantly lower in females compared with males. Greater post-ischemic ventricular function in female vs. male and ovariectomized hearts following DCD indicates that sex affects tolerance to DCD conditions and that female sex hormones contribute to cardioprotection. Greater understanding of sex-specific tolerance to DCD conditions may serve as a basis to better define precise mechanisms of cardiac injury and thereby contribute to optimizing clinical protocols.
