Normative data for Vietnamese population: Effects of age, education, and sex on test performance.
Article in Journal of the International Neuropsychological Society : JINS, 2025. 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
objectiveNormative data of neuropsychological tests in the Vietnamese population is considerably lacking. We aim to evaluate the effects of age, education, and sex on the performance of common neuropsychological tests, and to generate normative data for these tests in cognitively normal Vietnamese adults.
methodParticipants were recruited from two hospitals in Ho Chi Minh City, with inclusion criteria as follows: age ≥ 40 years, normal cognition and function, and Mini-Mental State Examination (MMSE) scores ≥ 26. Neuropsychological tests were administered in a paper-and-pencil format, including the CERAD Word List, Trail Making Tests, Digit Span, Animal Naming, and Clock Drawing Test. Effects of age, education, and sex on test performance were evaluated using multiple linear regression analyses. Normed scores were reported as regression-based and discrete norms tables.
resultsParticipants included 385 cognitively normal Vietnamese, with age 61.4 ± 10.9 years (range 40 - 89), female 56%, who were relatively highly educated (42% attended college and beyond, 36% attended high school or equivalent institutions, 22% had less than high school education), and had MMSE scores 27.8 ± 1.0. Trail Making Test Part B was completed within 300 s by only 204/385 (53%) participants. Regression analyses demonstrated significant associations between age and education with performance on all or most tests, and between sex and all CERAD Word List measures and Clock Drawing Test.
conclusionsThe present work provides the first known normative data for a relatively comprehensive neuropsychological battery in Vietnamese adults. Performance on all tests was significantly influenced by age and education.
