From: Up and down waves of glycemic control and lower-extremity amputation in diabetes

Fig. 1

Overview of the five NHANES waves (2000 to 2018) that assessed the prevalence of optimal glycemic control (HbA1c < 7%, red circles), incidence of LEA (lower-extremity amputations, number/1000/year, green circles) and prevalence of three risk factor (RF) control (HbA1c < 7%, non-HDL cholesterol < 130 mg/dl, blood pressure < 140/90 mm Hg, blue circles) in participants with diagnosed diabetes. The name perfect wave has been given to the central wave (2007–2010) because it was associated with the highest prevalence of participants in whom all three targets were simultaneously achieved, and the lowest incidence of LEA. The gray triangle at the end of the green curve indicates the possible scenario of LEA, as only data related to year 2015 are available
