Spearman correlation analyses
| Groups of Measures | Spearman rho or r2 | P Value |
|---|---|---|
| Whole-kidney MRE stiffness versus Banff fibrosis score | Rho =0.67 | <0.01 |
| Whole-kidney MRE stiffness versus baseline eGFR | Rho =−0.65 | <0.01 |
| Whole-kidney MRE stiffness versus history of prior or current rejection | Rho =0.39 | 0.13 |
| Whole-kidney MRE stiffness versus slope of eGFR change over the 12-mo follow-up period | Rho =−0.70 | 0.004 |
| Baseline eGFR versus slope of eGFR change over the 12-mo follow-up period | Rho =0.63 | 0.01 |
| Baseline urine albumin-to-creatinine ratio versus slope of eGFR change over the 12-mo follow-up period | Rho =−0.65 | 0.01 |
| Whole-kidney MRE stiffness as a predictor of the slope of eGFR change over the 12-mo follow-up period (regression analysis) | r2=0.48 | 0.03 |
Rho represents the strength of Spearman correlation, whereas r2 represents the strength of regression. MRE, magnetic resonance elastography.
