Anemia becomes increasingly prevalent as kidney function declines. Current treatments carry multiple safety risks. Sodium-glucose cotransporter 2 inhibitors (SGLT2i), dapagliflozin, have emerged as background anemia modulator, a promising alternative, showing protective effects against anemia. This study synthesizes evidence on dapagliflozin's potential to improve anemia in chronic kidney disease (CKD) patients. A systematic review and meta-analysis was performed according to Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines, including eight studies identified from six databases. Risk of bias was assessed using tools appropriate for each study design (RoB 2, NOS, JBI). Data were pooled using a random-effects model with RevMan 5.4. The primary analysis for hemoglobin demonstrated significant increase (MD = 4.37; 95% CI = 0.71-8.03; p = 0.02) and remained significant in the sensitivity analysis (MD = 4.11; 95% CI = 0.19-8.04; p = 0.04). A sensitivity analysis for hematocrit revealed a highly significant increase (MD = 2.15; 95% CI = 1.86-2.44; p p = 0.04). This finding was associated with significantly lower mortality (RR = 0.67; p = 0.02), while no significant differences were observed for cardiovascular (p = 0.22) or genitourinary events (p = 0.70). Dapagliflozin is associated with clinically meaningful improvements in hemoglobin and anemia outcomes in CKD. These findings suggest a potential erythropoietic benefit beyond glycemic control, although dedicated anemia-focused trials are needed to confirm clinical applicability.
