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

The neuroprotective effects of the course therapy with Histochrome in Wistar rats with modeled arterial hypertension were studied by using magnetic resonance imaging (MRI) in diffusion-weighted mode. The behavioral status of the animals was assessed using the open-field test. MRI analysis revealed more pronounced increase in the signaling characteristics of the brain tissue in hypertensive rats in comparison with the control (intact) animals. It was caused by excessive accumulation of fluid in the intra- and extracellular spaces of the brain tissue, which is associated with hypervolemia induced by the multifactorial cardiovasorenal model of hypertension. After a course of Histochrome injections to hypertensive rats, the cerebral microcirculation disorders were leveled, while the behavioral status was characterized by shortened latency of the visit to the center of the open field by 20% and improvement of cognitive activity (by 1.6 times) and the exploratory component (by 30%).
