Table A2.
Mean absolute T1ρ relaxation times of femoral and tibial cartilage subregions in response to loading. Mean ± standard deviation (ms) (mean percentage change versus δ0 (%)). Statistical analysis was performed using Friedman’s test and statistically significant findings are highlighted in bold type. Please refer to Table 2 for additional details on table organization.
