A retrospective observation study for the diagnostic effect of dual-source CT angiography on traumatic subarachnoid hemorrhage patients.

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
Identification of potential cerebrovascular disorder in the patient with traumatic subarachnoid hemorrhage (tSAH) is a key element to decrease the complication occurrence and mortality rate. In this study, we aim to compare the diagnostic values between dual-source computed tomography angiography (DSCTA) and traditional tomography angiography (CTA) in identification of potential cerebrovascular disorder among tSAH patients. A total of 113 tSAH patients with the hemorrhage involving more than 2 cisterns were recruited. Among that, 42 patients received DSCTA scans, and another 71 patients received traditional CTA scans. Subsequently, all patients received digital subtraction angiography (DSA) tests to confirm the presence of the cerebrovascular disorder. In DSCTA scan group, 21.4 % (9/42) patients were reported to have cerebrovascular disorders: seven patients had intracranial aneurysms; a patient had pseudoaneurysm with carotid artery cavernous sinus fistula; and a patient had Moyamoya disease. DSA tests had the same results with that with DSCTA scans. In the cohort receiving CTA scans, 19.7 % (14/71) patients were reported to had intracranial aneurysms. However, the positive results of DSA tests for this cohort were 22.5 % (16/71). Two inconsistent results between the CTA scan and DSA test were found, including an arteriovenous malformation and an arteriovenous fistula. In summary, DSCTA and CTA had similar positive rates but differ in diagnostic accuracy for identification of cerebrovascular disorders in tSAH patients.
