Table 2 Results of multivariable regression analysis for renal cortical perfusion prediction before backward elimination of insignificant variables.
Variable | Correlation coefficient (beta) | Regression coefficient | Significance-p |
---|---|---|---|
Age (years) | --- | --- | Adjusted |
MAP (mmHg) | 0.201 | 0.005 | 0.243 |
eGFR (ml/min/1.73 m) | 0.214 | 0.005 | 0.206 |
FT (pmol/L) | 0.494 | 0.047 | 0.004 |
eGFR – estimated glomerular filtration rate based on the CKD-EPI (chronic kidney disease-epidemiology) creatinine equation (2009); FT – thyroxine free hormone; MAP – mean arterial blood pressure. |
