Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
429 patients were recruited at St. Jude Children's Research Hospital between August 7, 2000 and July 27, 2006. 4 patients were found to be ineligible and 1 patient was taken off study per the PI's request. 424 patients were available at baseline.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
424 total patients were enrolled on the study. 149 patients were ineligible for randomization. 275 patients were identified with Bone Mineral Density (BMD) Z-scores > 0 and thus were eligible for intervention and were randomized to receive either Calcium and Vitamin D supplementation or placebo.

Reporting Groups
  Description
Placebo Group Nutritional counseling + placebo
Supplement Group Nutritional counseling + supplementation with calcium, 1000mg/day + vitamin D, 800 units/day, for a 2 year period
Patients Ineligible for Randomization 424 patients were enrolled into the study, 149 were ineligible for randomization.
