Instructions for Authors

Sep 2, 2026

Author instructions detailing structured manuscript requirements for multiple article types, including original articles, review articles, case reports, and clinical guidelines. The guideline-driven approach specifies expected abstract word limits, target manuscript word counts, and minimum references and tables/figures across categories such as CONSORT, TREND, STROBE, STARD, PRISMA, CARE, and AGREE. It supports consistent reporting standards for study types ranging from randomized trials to observational, diagnostic, and case report formats.
