Acute convexity subarachnoid hemorrhage (cSAH) in infectious endocarditis (IE): imaging features and follow-up.
Article in Journal of neurology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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.
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
aimTo assess: (1) the prevalence of convexity subarachnoid hemorrhage (cSAH) in infective endocarditis (IE); (2) its relationship with IE features; (3) the associated lesions; (4) whether cSAH is a predictor of future hemorrhage; (5) whether cSAH could cause cortical superficial siderosis (cSS).
methodsWe retrospectively evaluated the MRI data in 240 IE-patients: At baseline, the location of cSAH and associated lesions; at follow-up, the occurrence of new lesions and of cSS. Patients with and without cSAH were compared.
resultsThere were 21 cSAH-IE patients without (Group 1a) and 10 with intracranial infectious aneurysms (IIAs) (Group 1b). cSAH was revealed by headache (16.1%), confusion (9.7%), acute meningeal syndrome (3.2%) and was incidental in 71%. In most cases, the cSAH was: in the frontal (61.3%) and the parietal lobe (16.1%), unifocal, and mainly localized within a single sulcus (80.7%), appearing as a thick intrasulcal dark line on T2* in 70% of IIA patients. Valvular vegetations (87.1%, p < 0.0001), vegetations length ≥ 15 mm (58.1%, p < 0.0001) and mitral valve involvement (61.3%; p = 0.05) were significantly associated. There was no significant difference between the two groups in terms of pathogen distribution, valve characteristics and clinical expression. Associated lesions were: CMBs (77.4%), DWILs (51.6%), brain hemorrhages (16.1%) brain micro-abscesses (3.2%) meningitis (3.2%), visceral emboli (45.2%). At follow-up: no SAH recurrence or neurological event. cSS disappeared in 7/12 cases.
conclusioncSAH in IE is mostly an incidental finding but may be the telltale sign of an IIA. cSAH is not a marker of poor prognosis in non-IIA patients.
