Relationship between (a) estimated glomerular filtration rate (eGFR) and hemoglobin levels and (b) probability of anemia modeled by restricted cubic splines (cross‐sectional analyses). The data were adjusted for age, sex, history of smoking, types of diabetes (type 1 or type 2), history of hospitalization during a study period, diagnosis of malignancy, use of angiotensin converting enzyme inhibitors and/or angiotensin receptor blockers, use of iron supplementation, average monthly dose of erythropoiesis stimulating agents, mean corpuscular volume, mean corpuscular hemoglobin concentration, mean corpuscular hemoglobin, red cell distribution width, white blood cell counts, and platelet counts. Anemia was defined as hemoglobin <120 g/L for men and hemoglobin <110 g/L for women or the use of erythropoiesis‐stimulating agents. SGLT2i, sodium‐glucose cotransporter 2 inhibitors.
