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
objectivesCervicocerebral artery dissection (CAD) is one of the important causes for ischemic stroke in young and middle-aged people. CAD is dangerous and untimely diagnosis and treatment are likely to result in severe disability. Early diagnosis and timely intervention can greatly improve the prognosis of patients. This study was to investigate the imaging features of CAD on high-resolution magnetic resonance vessel wall imaging (HRMR-VWI) and to analyze the influential factors of vascular recanalization.
methodsA total of 19 CAD patients with both baseline HRMR-VWI and follow-up data of vascular imaging in the period from April 2017 to December 2019 in Department of Radiology, Xiangya Hospital, Central South University were retrospectively analyzed. The diseased vessels were divided into a recovery group and a unrecovered group. After treatment, diseased vessels with no residual arterial dissection and no residual stenosis in the lumen were included in the recovery group. Diseased vessels with stenosis, occlusion or residual dissection were included in the unrecovered group. Diseased vessels were divided into a ischemic stroke group and a non-ischemic stroke group according to the presence or absence of ischemic stroke in the area supplied by the diseased vessels. Differences in clinical data and HRMR-VWI imaging findings were compared between the groups.
resultsA total of 26 vessels were involved, including 14 (53.8%) internal carotid artery extracranial segment, 8 (30.8%) vertebral artery extracranial segment, 3 (11.5%) vertebral artery intracranial segment, and 1 (3.9%) basilar artery. Ischemic stroke occurred in 16 diseased vascular supply areas. Intramural hematoma was all observed in the baseline HMR-VWI of the affected vessels. There were 18 vessels (69.2%) in the recovery group and 8 vessels (30.8%) in the unrecovered group. Compared with the vessels in the recovery group, the vessels in the unrecovered group were mostly found in the intracranial segment (
conclusionsIntramural hematoma is a common imaging manifestation of CAD and can be shown clearly and accurately on HRMR-VWI. Recanalization rate of CAD is high, and the recanalization of CAD in intracranial segment is slower than that of CAD in extracranial segment, which can prolong the review time.
