Characteristics of acute occlusion of the intracranial vertebral artery and endovascular treatment.

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
To investigate the characteristics of acute occlusion of the intracranial vertebral artery (IVA) and endovascular treatment. Patients with acute IVA occlusion treated with endovascular thrombectomy were prospectively enrolled, and the clinical, treatment and 90-d data were analyzed. Forty-two patients were enrolled, with an age range 34-82 (57 ± 12) years, including 38 (90.48%) male and 4 (9.52%) female patients. Twenty-one (50.0%) patients underwent stent thrombectomy as the preferred recanalization technique, and 36 (85.7%) multiple modes of recanalization. Among the techniques used, balloon angioplasty was performed in 35 (83.3%) patients, stent implantation in 33 (78.6%), stent thrombectomy in 27 (64.3%), and thrombus aspiration in 6 (14.3%). The time from onset to first recanalization of blood vessels was 127-1517 [median 593.5 (326.3, 736.3)] minutes, and the time from puncture to first recanalization was 39-243 [median 67.0 (50.5, 81.3)] minutes. Successful recanalization with the mTICI grade 2b and 3 was present in 40 (95.2%) patients, including mTICI grade 3 in 25 (59.5%) and 2b in 15 (35.7%). Fifteen (35.7%) patients experienced periprocedural complications, including intraprocedural thrombus escape and embolism in 11 (26.2%) patients and symptomatic intracranial hemorrhage in 4 (9.5%). During 90-d follow-up, 16 (38.1%) patients obtained functional independence, 19 (45.2%) achieved good prognosis, and all-cause mortality was present in 9 (21.4%). Compared with patients with good prognosis, those with poor prognosis had significantly (P < 0.05) higher NIHSS scores but lower posterior communicating artery opening rate. Acute IVA occlusion is characterized by intracranial atherosclerosis and progressive stroke and can be successfully recanalized. High baseline NIHSS score and low posterior communicating artery opening rate may be related to poor prognosis.
