Symptomatic Non-stenotic Atherosclerotic Disease in Small Subcortical Infarcts: A North American Pilot Study.
Article in The Neurohospitalist, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Recent small subcortical infarcts (SSI) are a common radiographic predecessor to lacunar stroke. SSI is comprised of several pathophysiologic processes such as branch atherosclerotic disease (BAD) and lipohyalinosis, both of which have differing outcomes and natural history. Presently, there is not a proven method to determine whether a SSI is due to BAD or lipohyalinosis in non-stenotic vessels. However, high-resolution vessel wall imaging (HRVWI) has been reported in East Asian cohorts. We aimed to use HRVWI to identify individuals with BAD-related SSI in a North American cohort. We performed a cross-sectional study from the Rhode Island Hospital. All patients had a SSI as defined by consensus criteria. The presence of vessel wall enhancement of parent vessels were reviewed by two authors. Standard descriptive statistical techniques were used. Of 28 patients who underwent HRVWI, 7 met criteria for SSI. The median age was 68 years and 3 were female. Parent vessel wall enhancement was present in 2 patients. In our North American cohort, HRVWI was able to dichotomize individuals based on parent vessel wall enhancement suggestive of a BAD-related SSI. Further studies are needed to expand our cohort size and confirm our findings.
