Application of AI-assisted PBL-CBL combined teaching in the diagnosis and treatment of post-herpetic neuralgia: a randomised controlled trial.
Trial report 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
backgroundThis study aimed to explore the efficacy of a teaching model integrating artificial intelligence-assisted problem-based learning (PBL) with case-based learning (CBL) in standardized clinical teaching of postherpetic neuralgia (PHN) for medical interns.
methodsA total of 120 interns at the Affiliated Hospital of Yunnan University were randomly divided into an observation group and a control group (n = 60 each). The control group received conventional lecture-based teaching, while the observation group was taught using the AI-assisted PBL-CBL combined model. After four weeks of teaching, the educational outcomes were evaluated through theoretical examinations, clinical skill assessments, Mini-Clinical Evaluation Exercise (Mini-CEX) scores, and a teaching satisfaction questionnaire.
resultsAfter four weeks, the theoretical score of the observation group was 87.35 ± 5.66, and the clinical practice score was 90.12 ± 3.47, both significantly higher than those of the control group (84.67 ± 4.05 and 88.23 ± 3.94, respectively; P < 0.01). The Mini-CEX evaluation showed that students in the observation group had significantly improved clinical practice skills (P < 0.001), whereas no significant differences were observed between the two groups in humanistic qualities, professionalism, or organization/efficiency (P > 0.05). In addition, the observation group reported higher teaching satisfaction than the control group.
conclusionsThe AI-assisted PBL-CBL teaching model significantly improves medical interns' theoretical knowledge and clinical skills related to PHN, enhances their clinical reasoning ability, and increases teaching satisfaction.
