Journal Title: Eye Science (Yanke Xuebao) - Year 2020, Vol 35, Issue 5
Abstract
[Objective:] To evaluate the types of study design in clinical researches recently published in four Chinese general ophthalmology journals. [Methods:] A cross-sectional study. All articles on primary or secondary clinical study published in Chinese Journal of Ophthalmology, Chinese Journal of Experimental Ophthalmology, Recent Advances in Ophthalmology and Yan Ke Xue Bao in 2019 were reviewed after retrieved from WanFang Database. The research question and study design in each publication were assessed and evaluated. [Results:] A total of 353 primary clinical studies and systematic reviews were published in four journals in 2019, focusing on the top five diseases, including cataract, ametropia, keratopathy, glaucoma, diabetic retinopathy and diabetic macular edema. Retinal and vitreous diseases accounted for the largest proportion (26.6%) among subspecialties. The types of study design of 353 articles included 68 (19.3%) case reports, 107 (30.3%) case series studies, 86 (24.4%) cross-sectional studies, 21 (5.9%) case-control studies, 38 (10.8%) cohort studies, 8 (2.3%) non-randomized controlled trials, 22 (6.2%) randomized controlled trials (RCT) and 3 (0.8%) system reviews. Many of the publications unclearly stated or mis-labeled the types of study design. [Conclusion:] The articles of clinical research published in four Chinese general ophthalmology journals in 2019 focused on common and frequently-occurring ophthalmic diseases. The most common type of study design was case series, while analytical observational study and RCT were not frequently published. There is still plenty of room for improvement of the understanding, implementing and reporting clinical research in ophthalmology.
