Outcomes
Primary outcome [1] 335333 0
Difference in sympathetic tone before and after initiation of Sodium-glucose Cotransporter-2 (SGLT2) Inhibitors measured at weeks 0, 3, and 6. Difference in sympathetic tone is measured using a tungsten microelectrode inserted in a muscle fascicle of the peroneal nerve at the fibular head.

Efficacy
Statistical methods / analysis
continuous variables are expressed as mean ± standard deviation (SD) for normally distributed data or as median [interquartile range (IQR)] for non-normally distributed data, and as proportions for categorical variables.

Assessment of the difference in the value pre and post intervention will be assessed by paired T test.
