In contrast, other classes of AD were less well represented in the literature definitions of PIPs: DPP-4 inhibitors (n = 15, including 11 related to renal dysfunction), GLP-1 RAs (n = 15, including 12 related to renal dysfunction), and sodium-glucose transport protein 2 (SGLT-2) inhibitors (n = 14 including 13 related to renal dysfunction). This evidence concerns the gene DPP4 and Abnormal renal physiology.
