Objective This study aimed to examine the bibliometric over- view of articles published in the Medical Journal of Süleyman Demirel University between 2020 and 2025, and thereby to reveal the journal’s current pub- lication profile and developmental trends. Material and Method All articles published in the journal between Janu- ary 2020 and December 2025 were retrieved from the DergiPark archive and cross-checked with Goo- gle Scholar. Data were independently extracted by two researchers using a pre-specified coding form; disagreements were resolved by consensus. Cita- tions were retrieved on a single reference date (15 December 2025). Analyses were structured as a primary stream restricted to regular issues (n=438) and a supplementary stream including special issues (n=482). Departmental and institutional collaboration networks, as well as a keyword co-occurrence net- work, were constructed in Python (NetworkX). Group differences were tested with Pearson’s chi-square, Kruskal–Wallis and Mann–Whitney U tests, and Spearman correlations (α=0.05). Results In regular issues (n=438), 84.93% of articles were re- search articles, 7.53% case reports, 6.39% reviews, and 1.14% other. In the two special issues (n=44), reviews dominated (81.82%). The article-type mix, publication language, and study-design distribu- tion all shifted significantly across 2020–2025 (all p<0.05); notably, the English-language share rose from 33.8% in 2020 to 100% in 2025. A total of 176 articles (36.51%) received at least one Google Schol- ar citation. The departmental collaboration network revealed Pathology, General Surgery, Radiology, and Orthopedics & Traumatology as the most central nodes, forming a densely connected core of co-au- thoring clinical disciplines. The institutional network was dominated by Süleyman Demirel University as the central hub, with Isparta City Hospital and Meh- met Akif Ersoy University as its strongest col- laborators. The keyword co-occurrence network identified three clusters centred on (i) COVID-19/ pandemic, (ii) oxidative stress/apoptosis/inflamma- tion, and (iii) quality of life / nursing / psychosocial topics. Conclusion Research articles predominate in the journal, and interdisciplinary collaboration shows an increasing trend. The transition to English-only publication from mid-2024 is evident in the language distribution but cannot yet be evaluated in terms of citation impact; this will require longer follow-up. However, increasing the proportion of international publications and exper- imental studies could strengthen the journal’s scien- tific visibility.
