Design outcomes
Secondary
| Measure | Time frame |
|---|---|
| Secondary endpoints are the estimation of intrarenal hemodynamic parameters derived from Gomez equations, markers of tubular injury and changes in systemic hemodynamic properties. Additionally, the M-value as a marker of insulin sensitivity will be determined using a hyperinsulinemic euglycemic clamp technique. | — |
Primary
| Measure | Time frame |
|---|---|
| The main study parameters/endpoints are the measurement of glomerular filtration rate (GFR) and effective renal plasma flow (ERPF) as measured by iohexol and p-amminohippurate (PAH) clearance. | — |
