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

A 40-year-old man presented with thunderclap headache (TCH) and vomiting post-masturbatory ejaculation. He reported a similar episode with posterior neck pain five days earlier after ejaculation. Unlike his migraine history, these headaches were unusually severe. Upon arrival, physical and neurological examinations were unremarkable except for an elevated blood pressure (154/110 mmHg). Brain MRI/MRA systematically ruled out intracerebral/subarachnoid hemorrhages, aneurysms, cerebral venous thrombosis, and cervical artery dissection, with preserved flow voids on B-PASS, T2, and T2-FLAIR. Notably, MRA demonstrated multiple segmental vasoconstrictions compared to a baseline MRA from five years prior. With an RCVS
