- Vertebral fractures were graded using a semiquantitative method as mildly (1 point), moderately (1.5 point), and severely (2 points) deformed. Mildly deformed was defined as approximately 20–25% reduction in anterior, middle, and/or posterior height and a reduction of area 10–20%, moderately deformed as approximately 25–40% reduction in any height and a reduction of area 20–40%, and severely deformed as approximately over 40% reduction in any height and a reduction of area over 40%. The severity score was defined as total point of vertebral fractures
