Angiosome-targeted vs non-targeted endovascular revascularization in diabetic foot ischemia: A retrospective cohort study

Figure 1 Study flow diagram. Of 198 patients screened, 56 were excluded [non-diabetic etiology (n = 12), non-interventional management (n = 21), incomplete records (n = 14), and lost to follow-up before 3 months (n = 9)]. The final analytic cohort comprised 142 patients: Angiosome-targeted (direct; n = 33, 23.2%), non-targeted (indirect; n = 74, 52.1%), and combined (n = 35, 24.6%).
