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

Administration of 17β-estradiol has been shown to exert myocardial protective effects in hemorrhagic shock. We hypothesized that similar protective effects could help improve resuscitation from cardiac arrest. Three series of 18, 40, and 12 rats each, underwent ventricular fibrillation for 8 minutes followed by 8 minutes of chest compression and delivery of electrical shocks. In series-1, rats were randomized 1:1 to receive a bolus dose of 17β-estradiol (1 mg/kg) or 0.9% NaCl before chest compression; in series-2, rats were randomized 1:1:1:1 to receive a continuous infusion of 0.9% NaCl or a 17β-estradiol solution designed to attain a plasma level of 10(0), 10(2), or 10(4) nM during chest compression; and in series-3, rats were randomized 1:1 to receive a continuous infusion of 17β-estradiol to attain a plasma level of 10(2) nM or 0.9% NaCl during chest compression, providing inotropic support during the post-resuscitation interval using dobutamine infusion. 17β-estradiol failed to facilitate resuscitation in each of the 3 series. In series-1 and series-2, resuscitability and short-term survival was reduced in 17β-estradiol groups attaining statistical significance in series-2 when the three 17β-estradiol groups were combined (p = 0.035). In series-3, all rats were resuscitated and survived for 180 minutes aided by dobutamine which partially reversed post-resuscitation myocardial dysfunction but without additional benefits on myocardial function in the 17β-estradiol group. The present study failed to support a beneficial effect of 17β-estradiol for resuscitation from cardiac arrest and raised the possibility of detrimental cardiac effects compromising initial resuscitability and subsequent survival in a male rat model of ventricular fibrillation and closed chest resuscitation.
