Prevalence and Clinical Patterns of Central Post-stroke Pain Syndrome After Acute Ischemic Stroke: A Prospective Observational Cohort Study.
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
backgroundCentral post-stroke pain syndrome (CPSP) is a major neuropathic consequence after stroke, but the prevalence and clinical pattern are still inconsistently recorded. This study aims to investigate the prevalence, onset, and clinical presentation of CPSP after mild acute ischemic stroke.
methodsWe performed a prospective, hospital-based, observational cohort study of acute ischemic stroke patients. Development of CPSP was evaluated by clinical history, neurological examination, sensory profile, and neuroimaging correlation. Demographic variables, stroke characteristics, vascular risk factors, and functional outcome measures were analyzed.
resultsOf 720 acute ischemic stroke patients prospectively screened, 100 (13.9%, 95% CI 11.4-16.4%) met diagnostic criteria for CPSP and were included in the analysis. The mean age was 64.8 ± 7.1 years, and 63 (63.0%) were male. Middle cerebral artery territory lesions were most common (43.0%), followed by thalamic lesions (21.0%). Pain was contralateral to the stroke lesion in 98.0% of patients. In multivariable logistic regression, a higher NIHSS (National Institutes of Health Stroke Scale) score independently predicted poorer functional outcome (modified Rankin Scale (mRS) 2) at follow-up (OR: 2.915, 95% CI: 1.525-5.573, p = 0.001).
conclusionCPSP is a clinically significant complication after acute ischemic stroke and should be actively screened during follow-up. Early recognition can improve symptom management and rehabilitation outcomes.
