1 · What the graph read from it

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.

2 · The registry

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

objectiveTo compare the safety and efficacy of self-expandable stents (SES) and balloon-mounted stents (BMS) in the treatment of severe symptomatic intracranial vertebral artery atherosclerotic stenosis (SIVAAS).

methodsThe clinical and imaging data of 76 consecutive cases who were stented for SIVAAS in our centers in ten years were reviewed retrospectively. The cases were divided into SES group and BMS group as per the type of stents. Conventional risk factors of atherosclerosis, the relationship between stenosis and the origin of posterior inferior cerebellar artery (PICA), whether the stenosis was located at the dural-entry zone of the vertebral artery (VA), the interventional access, periprocedural complications, and clinical and imaging follow-up results were analyzed statistically.

results77 stenotic lesions in 76 cases were included. Totally 51 SES and 26 BMS were implanted successfully. There was no significant difference in periprocedural complications (1 vs. 2, P = 0.544), incidence of restenosis (13.2% vs. 14.3%, P = 0.628) and long-term death or stroke (4 vs. 7, P = 0.33) between the two groups. The degree of residual stenosis in SES group was higher than in BMS group (10 (0%-40%) vs. 0 (0%-15%); P = 0). More BMS were selected in lesions located at the dural-entry zone of VA (45.1% vs. 73.1%, P = 0.02). There were more BMS implanted when lesions located proximal to origin of PICA (SES vs. BMS = 23.5% vs. 57.7%, P = 0.003) or when lesions with straighter access (SES vs. BMS = 29.4% vs. 69.2%, P = 0.001). More SES implanted when lesions located distal to PICA (SES vs. BMS = 43.1% vs. 15.4%, P = 0.015) or when lesions with moderate tortuous access (SES vs. BMS = 60.8% vs. 23.1%, P = 0.002). For stenotic lesions with moderate tortuous interventional access, SES group cases had longer survival time without stroke or death (P = 0.008).

conclusionBoth SES and BMS showed high safety and efficacy for the treatment of SIVAAS. SES was more recommended for the stenotic lesions with tortuous interventional access. BMS was more recommended for the lesions located at the dural-entry zone of VA or proximal to PICA origin.
