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.
