Impact of a research methodology course emphasizing critical appraisal skills on dental students' clinical decision-making self-efficacy: a single-arm educational intervention.
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
backgroundUndergraduate dental education in India emphasizes procedural competence, with limited structured exposure to research methodology and evidence appraisal. Research-oriented learning develops analytical reasoning, critical appraisal, and evidence interpretation skills that parallel core clinical reasoning processes and may strengthen students’ confidence in applying research evidence to patient care. The goals of this project were to implement a structured research methodology course emphasizing the critical appraisal process central to evidence-based practice (EBP), and assess its impact on clinical decision-making self-efficacy among undergraduate dental students.
methodsA prospective, single-center, single-arm quasi-experimental pre–post educational intervention study was conducted over 12 weeks among 250 undergraduate dental students. The research methodology course that comprised the education intervention was grounded in the principles of constructivism and competency-based education, incorporating blended learning, mentorship, and applied clinical scenarios. Clinical decision-making self-efficacy and research awareness were assessed using a validated 14-item questionnaire administered before and after the intervention. Statistical analyses included non-parametric pre–post comparisons, effect size estimation, subgroup analyses, and correlation testing. Ethical approval was obtained (MRDC/IEC/2025/58), and the study adhered to appropriate reporting guidelines for educational intervention research.
resultsClinical decision-making self-efficacy scores increased significantly from baseline to post-intervention (21.3 ± 3.8 to 28.9 ± 3.6; p < 0.001; Cohen’s d = 1.05). Research awareness scores also improved significantly (19.1 ± 4.2 to 27.4 ± 3.9; p < 0.001; Cohen’s d = 1.12). Improvements were observed across all academic years, with greater gains among senior students. Post-intervention feedback indicated high satisfaction and perceived clinical relevance.
conclusionImplementation of a structured research methodology course emphasizing critical appraisal of evidence via active learning strategies was associated with improved clinical decision-making self-efficacy among dental students, supporting the integration of research training into undergraduate dental education.
