Validity, reliability and diagnostic accuracy of the Thai version of the cognitive assessment scale of stroke patient (T-CASP) in non-aphasic stroke.
Article in BMC research notes, 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
objectivesThis study aimed to translate, culturally adapt the Cognitive Assessment Scale for Stroke Patients into Thai (T-CASP). It is also aimed to evaluate the psychometric properties, including validity, reliability, and diagnostic accuracy, for detecting post-stroke cognitive impairment (PSCI) among patients with non-aphasic stroke.
resultsA total of 66 stroke patients from a neurology clinic completed the Thai Mental State Examination (TMSE), Montreal Cognitive Assessment (MoCA), and T-CASP. All participants scored above the cutoff on the TMSE; therefore, the MoCA was used as the reference instrument. T-CASP scores showed a strong positive correlation with the MoCA (r = 0.71, p < 0.001). Internal consistency of the original T-CASP was acceptable (Cronbach's α = 0.67) and improved after removal of items C2 (Comprehension) and C4 (Drawing a picture series) (Cronbach's α = 0.72). Test-retest reliability was excellent for both the original version (ICC = 0.89) and the modified version excluding items C2 and C4 (ICC = 0.87). Both versions demonstrated high diagnostic performance, with sensitivity of 79.5% and 72.7%, specificity of 95.5% and 99.5%, and area under the ROC curve values of 0.87 and 0.84, respectively. Taken together, these findings suggest that the T-CASP shows promise as a screening tool for PSCI in Thai patients.
