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

backgroundThere is controversy whether asymptomatic vasospasm in other arteries should be concurrently treated (global treatment) in patients receiving targeted endovascular treatment [percutaneous-transluminal-angioplasty (PTA) and/or intra-arterial (IA) vasodilators] for focal symptomatic vasospasm.

objectiveTo determine the rates of occurrence of new symptomatic vasospasm in previously asymptomatic arterial distributions among patients with aneurysmal subarachnoid hemorrhage (SAH) who underwent targeted endovascular treatment for focal symptomatic vasospasm.

methodsWe identified all patients with SAH who had received targeted endovascular treatment during a 4-year period. We ascertained any new occurrence of symptomatic vasosopasm requiring endovascular treatment in previously unaffected (and untreated) arterial distributions within the same hospitalization. Blinded reviewers quantitatively graded angiographic vasospasm (<25, 26-49, ≥50 %) in all major arteries for each patient at the time of targeted treatment.

resultsOf the 41 patients who received targeted endovascular treatment (PTA in 41 % and vasodilators in 59 %), 11 (27 %) developed new symptomatic vasospasm in previously asymptomatic vascular distributions requiring endovascular treatment. Moderate severity of angiographic vasospasm in asymptomatic arteries at the time of targeted treatment tended to predict the occurrence of new symptomatic vasospasm. The rate of death and disability at discharge [modified Rankin scale (mRS) of 3-6] was 82 % (9/11) among those who developed a new episode of symptomatic vasospasm compared with 70 % (21/30) in those who did not (P = 0.58).

conclusionsHigh risk of new occurrence of ischemic symptoms in previously asymptomatic (and untreated) arterial distributions among patients receiving targeted treatment should be recognized. Further studies should evaluate the benefit of performing global endovascular treatment during the initial targeted endovascular treatment session.
