Distribution of total BML volume change when stratified by tertiles based on total baseline BML volume
| Total BML volume change (by quartile with middle two quartiles collapsed) | ||||
|---|---|---|---|---|
| Total baseline BML volume | Total BML volume change Median (min, max) cm3 |
'BML regression' (Range: -12.7 to -0.8 cm3) n (% of baseline tertile) |
'Minimal or no BML change' (Range: -0.8 to 0.4 cm3) n (% of baseline tertile) |
'BML progression' (Range: 0.4 to 10.2 cm3) n (% of baseline tertile) |
| 'No or Small BML volume' (Range: 0.1 to 1.0 cm3) |
0.0 (-0.7, 4.2) | 0 (0.0%) | 108 (80.6%) | 26 (19.4%) |
| 'Moderate BML volume' (Range: 1.0 to 2.7 cm3) |
-0.1 (-2.5, 5.0) | 24 (17.8%) | 68 (50.4%) | 43 (31.9%) |
| 'Large BML volume' (Range: 2.7 to 15.5 cm3) |
-1.1 (-12.7, 10.2) | 77 (57.0%) | 26 (19.3%) | 32 (23.7%) |
The division of total baseline bone marrow lesion (BML) volume and total BML volume change was based on tertiles. n = 404.
