Comparison of hemodynamic changes and prognosis between stenting and standardized medical treatment in patients with symptomatic moderate to severe vertebral artery origin stenosis.
Observational study in Medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
This study aimed to compare the clinical efficacy of stenting compared with standardized medical treatment in patients with moderate to severe vertebral artery origin stenosis (VAOS).Patients diagnosed with moderate to severe VAOS and indicated to undergo vertebral artery stenting were enrolled. Patients were divided into stenting group and standardized medical treatment group. All patients underwent transcranial Doppler (TCD) before and after treatment. Incidence of new cerebral infarction, transient ischemic attack (TIA), improvement of clinical symptoms, and National Institutes of Health Stroke Scale (NIHSS) score were observed.A total of 98 patients were enrolled. Vertebral artery stenting implant was accepted by 43 patients. Two weeks after treatment, the NIHSS score in the stenting group decreased significantly compared to that in the standardized medical treatment group. The modified Rankin Scale (mRS) score in the stenting group at three months was significantly lower than that in the medical treatment group (P = .044). The extent of vascular stenosis in the stent group decreased significantly (76.5 ± 10.0% vs. 13.7 ± 5.9%, t = 35.878, P = .000). The adverse events occurred in 9 (16.4%) patients in the medical treatment group and 5 (11.6%) in the stenting group (P = .506). There was one case with new cerebral infarction in the stenting group, whereas the medical treatment group showed 1 case with TIA and three with new cerebral infarction during follow-up after 3 months. The peak systolic velocity (PSV), end diastolic velocity (EDV), pulsatility index (PI) of stenosis vertebral artery, and PSV of basilar artery were significantly higher in the stent group than those in the standardized medical group (P < .05).Stenting for VAOS, rather than standardized medical treatment, can effectively relieve vascular stenosis, alter vertebral-basilar artery hemodynamics, and improve neurological function, with low perioperative complications.
