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

BACKGROUND AND

objectiveCerebral vasospasm is a common and serious complication of aneurysmal subarachnoid haemorrhage (SAH). Many studies have revealed a role of inflammation in the development of cerebral vasospasm. This study aimed to investigate whether topically administered dexamethasone could attenuate vasospasm in SAH patients.

methodsPaired samples were designed to compare postoperative mean middle cerebral artery velocity between treated patients and controls matched for age (+/-10 years), sex, location and size (small, medium or large) of aneurysm, as well as baseline mean middle cerebral artery velocity. We enrolled ten consecutive aneurysmal SAH patients who had Hunt-Hess (HH) grade 3 and Fish grade 3 lesions and were admitted within 24 hours following the onset of SAH. These patients were treated with dexamethasone 10mg topically at the end of the operation. Each treated patient was matched with a control patient who did not receive topical dexamethasone. All controls also had HH grade 3 and Fish grade 3 SAH and were admitted within 24 hours after the onset of SAH. Serial measurements of mean middle cerebral artery velocity were performed postoperatively every day for 2 weeks. Results were analysed with the paired t-test.

resultsOne patient (10%) in the treated group had vasospasm, without neurological deficit, compared with four patients (40%) in the control group, one of whom had hemiplegia. Paired t-test showed that the mean middle cerebral artery velocity in controls was significantly higher than that in treated patients on days 4-14.

conclusionTopical application of dexamethasone is a promising strategy for prevention and attenuation of vasospasm following aneurysmal SAH.
