Small Pontine Infarction Secondary to Posterior Inferior Cerebellar Artery (PICA) Atherosclerosis: The Diagnostic Value of 3 Tesla MRI.
Article in Cureus, 2026. 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
Posterior circulation strokes, particularly those involving the posterior inferior cerebellar artery (PICA), often present with nonspecific symptoms, such as vertigo, frequently leading to misdiagnosis as peripheral vestibular disorders. Identifying small lacunar infarcts in these regions requires high-resolution neuroimaging. A 65-year-old female with a history of hypertension and dyslipidemia presented with sudden-onset rotatory vertigo, headache, and right-sided paresthesia (National Institutes of Health Stroke Scale {NIHSS}=2). The 3 Tesla MRI revealed a 5-mm acute ischemic focus in the left pons on diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) sequences. Three-dimensional (3D) time-of-flight (TOF) magnetic resonance angiography (MRA) demonstrated multifocal atherosclerotic stenosis along the left PICA. The patient was managed with dual antiplatelet therapy (DAPT) (clopidogrel 75 mg and aspirin 100 mg), high-intensity statin (rosuvastatin 20 mg), and stringent blood pressure control. Following seven days of treatment, clinical symptoms improved significantly, and the patient was discharged in stable condition. The 3 Tesla MRI is a pivotal tool for detecting small-core infarcts and evaluating detailed atherosclerotic changes in the posterior circulation. Integrating clinical vigilance with advanced imaging facilitates accurate diagnosis and optimizes medical management to prevent recurrent stroke.
