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: Initial angiography may not identify a bleeding source in some subarachnoid hemorrhage (SAH) cases. We report an instructive case of initially angiogram-negative SAH where an anterior communicating artery aneurysm became apparent during treatment for vasospasm, subsequently requiring successful endovascular embolization. Case Description: A woman in her 60s presented with diffuse SAH (Fisher group 3); initial computed tomography angiography (CTA) and digital subtraction angiography were negative for aneurysms. Symptomatic vasospasm developed on day 4, and treatment including cilostazol and fasudil was initiated. A repeat CTA on day 8 revealed the aneurysm. Conclusion: This case underscores that even with negative initial angiography, an underlying aneurysm should be strongly suspected in patients with diffuse SAH or subsequent vasospasm. It highlights the critical importance of meticulous follow-up and appropriately timed, high-quality imaging re-evaluation, which can lead to accurate diagnosis and favorable outcomes.
