Exploring cognitive ability and non-cognitive intelligence associated with preclinical academic performance: a study of Thai medical students.
Article in BMC medical education, 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
backgroundUnderstanding factors associated with academic performance in medical students is important for optimizing admission processes and improving medical curricula. This study aimed to examine the associations between cognitive and non-cognitive factors and academic achievement during the preclinical years of medical education.
methodsA total of 194 medical students admitted in the academic years 2022 and 2023 at the Faculty of Medicine, Prince of Songkla University, Thailand, were included. Cognitive factors included pre-medical grade point average (GPA), Thai University Central Admission System (TCAS) scores, and cumulative GPA (cGPA) during the preclinical years. Non-cognitive factors, including empathy, emotional intelligence, and social awareness, were assessed by psychiatrists during admission interviews. Academic achievement was defined as passing the Thai National Licensing Examination (NLE). Associations between student characteristics, admission scores, and NLE outcomes were analyzed using the Chi-square test, Fisher’s exact test, Student’s t-test, or Mann-Whitney U test, as appropriate; a p-value of < 0.05 was considered statistically significant.
resultsOf the 194 students included in the analysis, 51.5% were male. The median pre-medical GPA was 3.87 (interquartile range [IQR]: 3.72–3.95), while the median preclinical cGPA was 3.31 (IQR: 3.00-3.55). Overall, 89.2% of students passed the Thai NLE. Students who passed the examination had significantly higher preclinical cGPAs than those who failed (p < 0.001). In multivariable analysis, a higher preclinical cGPA was independently associated with increased odds of passing the NLE (adjusted odds ratio [OR] = 1.98; 95% confidence interval [CI]: 1.58–2.70). No significant associations were observed between NLE outcomes and other cognitive factors, including pre-medical GPA and TCAS subject scores, nor with non-cognitive factors such as empathy (p = 0.948), emotional intelligence (p = 0.557), and social awareness (p = 0.887).
conclusionPreclinical academic performance, as measured by cGPA, was strongly associated with success on the Thai NLE. These findings highlight the importance of preclinical education in preparing students for licensure examinations. Admission performance and non-cognitive traits were not significantly associated with NLE outcomes, which may reflect limitations in the assessment tools employed in this study.
