Fig. 4From: Cardiovascular benefits of SGLT2 inhibitors in type 2 diabetes, interaction with metformin and role of erythrocytosis: a self-controlled case series studyForest plot of incidence rate ratios of study outcomes by exposure of metformin and SGLT2i. The incidence rate ratio of study outcomes between periods of (i) metformin use without SGLT2i; (ii) pre-SGLT2i (three months before each initiation of SGLT2i); (iii) SGLT2i use alone period; and (iv) combined use of metformin and SGLT2i period, were estimated using conditional Poisson regression model with an offset for the length of the risk period, with adjustment of time-varying factors (age and the use of other anti-diabetic agents [sulfonylureas, thiazolidinediones, dipeptidyl peptidase-4 inhibitors, GLP1 receptor agonists, and insulin])Back to article page
