Fisher R to Z transformation.
| Variable | Computed Tomography vs Lateral DEXA | Anterior to Posterior DEXA vs Lateral-DEXA | Computed Tomography vs Anterior to Posterior-DEXA |
| R 2 | 0.78 vs 0.40 | 0.70 vs 0.40 | 0.78 vs 0.70 |
| P | 0.009 | 0.032 | 0.120 |
| Z-score | 2.371 | 1.857 | 0.171 |
Abbreviation: DEXA, dual-energy x-ray absorptiometry.
Note: Calculation of the difference between 2 correlation coefficients with 1 variable in common using 1-tailed Steiger Z test.
