Table 4.
Sex differences in CT density changes (n = 56)
| Men (n = 29) | Women (n = 27) | p value | |
| Upper Zone | -0.6 | -2.2 | p = 0.006 |
| Perc15 (HU) | (-2.11 to 0.8) | (-5.2 to -0.7) | |
| Upper Zone | 0.17 | 0.46 | p < 0.03 |
| VI -950HU (%) | (-0.27 to 0.70) | (0.15 to 1.08) | |
| Lower Zone | 0.23 | -1.89 | p < 0.05 |
| Perc15 (HU) | (-1.68 to 1.71) | (-5.67 to 0.03) | |
| Lower Zone | 0.12 | 0.24 | not significant |
| VI -950HU (%) | (-0.17 to 0.57) | (0.04 to 0.79) |
The data was not normally distributed and therefore is presented as median with interquartile range in parentheses. All values are presented as a standardized annual rate of change.
VI = voxel index, Perc15 = 15th percentile point, HU = Hounsfield Units
