The Knowledge-Attitude Paradox in Analgesic Self-Medication Among University Students in Ecuador: A Cross-Sectional Study and Predictive Modeling Analysis.
Article in Public health challenges, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Objective: To evaluate the prevalence and determinants of analgesic self-medication among university students in Ecuador, with a focus on the interplay between pharmacological knowledge and personal attitudes. Methods: A cross-sectional analytical study was conducted with 422 students at Universidad Tecnologica Indoamerica (April-August 2025), selected via stratified random sampling. A validated, structured questionnaire assessed knowledge, attitudes, and practices. Multivariable logistic regression and random forest algorithms were employed to identify key predictors and their relative importance. Results: The prevalence of analgesic self-medication was exceptionally high at 87.5%. Random forest analysis identified attitude as the primary predictor of this behavior (relative importance = 0.252), followed by academic year and pharmacological knowledge. A significant "knowledge-attitude paradox" was observed, wherein health sciences students, despite possessing superior pharmacological knowledge, exhibited the highest rates of self-medication. The predictive model demonstrated excellent discrimination (AUC = 0.81). Conclusion: The high prevalence of self-medication, a finding consistent with emerging international data, necessitates a fundamental paradigm shift in public health interventions. Educational strategies must evolve beyond simple information dissemination to incorporate behavioral science principles aimed at modifying attitudes and risk perceptions, particularly during the formative early years of university education.
