Observational study in Acta neurologica Belgica, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06218576 (Sensitivity Comparison of Follow-up MRI Between Acute Cerebral and Cerebellar Cortical Microinfarctions), which is not on this map. Not yet cited in PubMed.

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.

Abstract

backgroundDetection rate of chronic cerebral very small cortical infarctions (VSCI) is low. Few data are available on chronic cerebellar VSCI. Our aim was to study the ability of 1.5T FLAIR and T2-weighted imaging to detect chronic VSCI and compare cerebral and cerebellar VSCI location.

methodsWe prospectively included stroke patients with ≥ 1 acute cerebral or cerebellar VSCI ≤ 10 mm on DWI. Follow-up FLAIR and T2-weighted imaging with the same 1.5T-magnet was performed after six months. Images were evaluated unblinded to initial MRI to detect signal changes at the same location as initial acute VSCI. Variables influencing chronic VSCI detection were analyzed in uni- and multivariate analyses.

resultsWe analyzed 57 patients (median age 65, 44% women) with 111 acute VSCI on initial MRI. These constituted 47 cerebellar and 64 cerebral acute VSCI, with median DWI size of 5.9 mm and initial FLAIR positivity of 70%, without difference between cerebellar and cerebral location. On 6-month follow-up MRI, chronic VSCI detection on FLAIR and T2 was similar for cerebral lesions (p = 0.81), whereas for cerebellar lesions T2 showed a 2.4-fold higher detection rate than FLAIR (p < 0.0001). Univariate analysis using a logistic mixed model for T2 detection of chronic VSCI was associated with cerebellar VSCI location (p < 0.0001) and hypertension history (p = 0.008). Multivariate analysis confirmed the strong association between cerebellar location and T2 detection of chronic VSCI (p < 0.0001, AOR = 7.25, 95% CI = 2.83-18.56) adjusted for hypertension.

conclusionCompared to FLAIR, T2-weighted imaging shows highest detection rates for cerebellar VSCI, with cerebellar VSCI location as strongest predictor of chronic VSCI detection. CLINICAL
