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

backgroundMinocycline provides neurovascular protection reducing acute cerebral injury. However, it is unclear whether minocycline is effective in females. We tested minocycline in both sexes and aged animals using a novel embolic stroke model in mice that closely mimics acute thromboembolic stroke in humans.

methodsFive groups of mice were subjected to thromboembolic stroke: adult males, aged males, adult females, aged females, and adult ovariectomized females. They were treated with phosphate saline (vehicle) or minocycline (6 mg/kg) immediately after stroke onset. Behavioral outcomes, infarct volumes and cerebral blood flow were assessed. The effect of minocycline on expression and activity of MMP-9 was analyzed.

resultsThe model resulted in reproducible infarct in the experimental groups. As expected, adult females were significantly more resistant to cerebral ischemic injury than males. This advantage was abolished by aging and ovariectomy. Minocycline significantly reduced the infarct volume (P < 0.0001) and also improved neurologic score (P < 0.0001) in all groups. Moreover, minocycline treatment significantly reduced mortality at 24 hours post stroke (P = 0.037) for aged mice (25% versus 54%). Stroke up-regulated MMP-9 level in the brain, and acute minocycline treatment reduced its expression in both genders (P < 0.0001).

conclusionIn a thromboembolic stroke model minocycline is neuroprotective irrespective of mouse sex and age.
