Correlation between OA severity and microstructural parameters in all quadrants in cortical bone.
| Quadrants | BV/TV | BS/BV | Po(tot) | Cs.Th | TMD | |||
|---|---|---|---|---|---|---|---|---|
| 1 | 3 | 1 | 3 | 1 | 3 | 3 | 2 | |
| r | − 0.71 | − 0.65 | 0.56 | 0.60 | 0.71 | 0.65 | − 0.85 | − 0.62 |
| p | 0.01 | 0.02 | 0.04 | 0.03 | 0.01 | 0.02 | 0.000 | 0.02 |
BV/TV: bone volume fraction; BS/BV: specific bone surface; Po (tot): total porosity; Cs.Th: cortical thickness, TMD: tissue mineral density. The correlation coefficient, r, and p values are reported. p < 0.01 was considered significant.
