T score is the number of standard deviations above or below the mean for a healthy 30 year old adult of the same sex and ethnicity as a participant. This score is calculated from participant's age, gender and race and skeletal site. T score has a mean of '50' and a standard deviation of '10'. T score lower than its mean indicate low bone mineral density.","dispersionType":"Standard Deviation","groups":[{"description":"bortezomib (Velcade) 1.6 mg/m² bolus injection on Days 1, 8, 15 and 22 every 5 weeks for 4 cycles","id":"OG000","title":"Bortezomib"},{"description":"no treatment, observation only","id":"OG001","title":"Non-treated Control"}],"paramType":"MEAN","populationDescription":"FAS included all the randomized subjects who were eligible for efficacy analysis, that is, excluding subjects who did not have baseline and/or post-baseline data. \"N\" (number of subjects analyzed) signifies the subjects evaluable this measure.
