Abstract

This study aimed to explore the relationship between diabetic retinopathy (DR) and diabetic foot ulcers (DFUs) to provide evidence for the prevention of diabetic complications. PubMed, EMBASE, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Chinese Biomedical Literature Database and Wanfang Data databases were searched from their inception until March 2023 for studies on the relationship between DR and DFU. Two researchers independently screened the literature and extracted data according to the inclusion and exclusion criteria. The meta-analysis was performed using the RevMan 5.3 software. Eleven articles referring to 10 208 patients were included, of whom 2191 patients had DFU and 8017 patients did not have DFU. The meta-analysis results showed that DR significantly increased the incidence of DFU (47.94% vs. 16.38%; OR, 4.13; 95% CI, 2.33-7.33; p < 0.001). The results of this study suggest that patients with DR have a higher risk of developing DFU, highlighting the importance of regular screening for these two complications to prevent serious adverse outcomes of diabetes. However, further high-quality studies are required to validate the conclusions of the present study.
