Analysis of the growth trajectories of junior residents in Japan: a longitudinal cohort study using data from a nationwide e-portfolio system (EPOC2).
Article in BMJ open, 2025. 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
objectivesAs more emphasis is placed on the acquisition of competencies in medical education, portfolios are increasingly being used for evaluation. EPOC2 (E-POrtfolio of Clinical training) is an e-portfolio system developed in Japan and is used by about 800 clinical training hospitals. The study objective is to identify the learning trajectory of junior residents to provide insights into the provision of better postgraduate and undergraduate medical education in Japan.
designLongitudinal cohort study.
settingHospitals nationwide adopting EPOC2.
participants7671 residents who participated in clinical training programmes at hospitals adopting EPOC2 between April 2020 and March 2022. PRIMARY OUTCOME MEASURE: Formative evaluation scores assessed through self-evaluation by junior residents and evaluations by supervisors/senior physicians at the end of each rotation in each clinical department.
resultsFor all evaluation items, growth trajectories were divided into six groups, each with distinct characteristics based on the specific content of the evaluation form. For example, in the self-evaluation of medical knowledge and problem-solving (B-2), a lower percentage of respondents had adequate scores at the beginning of their training compared with other similar items. Compared with the self-evaluations of the other item groups (ie, forms A1-A4 and B1-B9), the self-evaluation of the item group related to seeing patients (ie, forms C1-C4) differed by showing a group that remained at or below 2 until the end, accounting for 2.8% to 7.0%, possibly indicating the relatively low confidence of the residents for these items.
conclusionsGrowth trajectories fall into six groups, each with its own characteristics depending on the content of the items. These findings offer valuable insights into the developmental trajectories of junior residents and may highlight opportunities for enhancing their training programmes in Japan. This underscores the usefulness of a nationwide evaluation system, enabling researchers to analyse clinical education outcomes across the country using uniform indicators.
