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

Experimental studies have demonstrated protective effects of NHE-1 inhibition on cardiac function; however, clinical trials utilizing NHE-1 antagonists found an increase in overall mortality attributed to thromboembolic strokes. NADPH oxidase-derived reactive oxygen species (ROS) from microglial cells have been shown to contribute to injury following stroke. We have recently demonstrated that NHE-1 inhibition enhances ROS in macrophages in a Hv1-dependent manner. As Hv1 protein is highly expressed in microglia, we hypothesized that "NHE-1 inhibition may augment neurovascular injury by activating Hv1," providing a potential mechanism for the deleterious effects of NHE-1. The goal of this study was to determine whether neurovascular injury and functional outcomes after experimental stroke differed in wild-type and Hv1 mutant Dahl salt-sensitive rats treated with an NHE-1 inhibitor. Stroke was induced using both transient and permanent of middle cerebral artery occlusion (MCAO). Animals received vehicle or NHE-1 inhibitor KR32568 (2 mg/kg, iv) either 30 min after the start of MCAO or were pretreated (2 mg/kg, iv, day) for 3 days and then subjected to MCAO. Our data indicate that Hv1 deletion confers both neuronal and vascular protection after ischemia. In contrast to our hypothesis, inhibition of NHE-1 provided further protection from ischemic stroke, and the beneficial effects of both pre- and post-treatment with KR32568 were similar in wild-type and Hv1
