Differences in substance abuse knowledge and awareness by year of study among medical students.
Article in BMC primary care, 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
objectiveAs future healthcare providers, medical students play a critical role in the prevention, early recognition, and management of substance use disorders. However, the extent to which they are adequately prepared for this responsibility remains insufficiently explored. This study aims to evaluate differences in knowledge and awareness according to year of study.
methodsA total of 607 students (399 first-year and 208 sixth-year) from a medical faculty were included in the study. Data were collected through structured face-to-face interviews using the Substance Abuse Awareness Scale (SAAS) and the Substance Abuse Knowledge Test (SAKT). Descriptive statistics and correlation analyses were performed (p < 0.05).
resultsThe mean participant age was 20.4 ± 2.6 years, with 54.5% identifying as female. Despite the high rate of formal education (87.0%), variability in knowledge and awareness levels remained evident. The mean scores were 23.0 ± 6.6 for the SAKT and 114.1 ± 12.0 for the SAAS, with the latter demonstrating high internal reliability (Cronbach's alpha = 0.873). Age positively correlated with SAKT scores and the Help and Legal Regulations subscale of the SAAS, whereas no significant correlation was found with other SAAS subscales or the total SAAS score. Female students scored higher on several scales. Grade level significantly influenced awareness across all SAAS subdomains, excluding Symptoms and Effects of Substance Use. No significant relationships were found between outcomes and parental education, family structure, or personal history of smoking and alcohol use. Students who had received curricular education on substance use demonstrated significantly higher knowledge levels.
conclusionKnowledge and awareness levels differed by year of study, with higher scores observed in senior students. However, targeted improvements-particularly in recognizing symptoms and health effects-are warranted to better equip future physicians for their roles in prevention, early detection, and public health advocacy.
