Abstract
Physician-scientists link clinical investigation with biomedical discovery, yet sustaining research engagement across training and early career remains challenging. We conducted a structured evidence synthesis of physician-scientist training in China and selected comparator systems. PubMed and Web of Science searches covering 2010-2025 yielded 3,639 records; after deduplication, screening, and adjudication, 90 primary empirical studies were included, comprising 73 with direct physician-scientist evidence and 17 with supportive residency-context evidence. Research exposure varied across pathways and programs. Chinese residency studies documented substantial training burden, while formal protected research time was not consistently identified in reviewed residency settings, positioning residency as a plausible constraint on research continuity without establishing causality. The transition from structured training toward research independence also emerged as a recurrent vulnerability involving discontinuities in protected research opportunity, mentorship, and career-development support. Across systems, protected research opportunity, transition support, funding continuity, and early-career support recurred as structural features, with implementation varying by system, institution, program, and career stage. These findings support research continuity as an organizing framework and identify structural mechanisms warranting prospective evaluation rather than universal prescription.

Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.
Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
