Data are expressed as means (SD) (mixed model for repeated measures). C-SLE, childhood-onset systemic lupus erythematosus; PRE, pre-intervention (baseline), POST, post-intervention; BMAD, bone mineral apparent density; BMC, bone mineral content; TF, total femur; L1-L4, lumbar vertebrae L1 to L4; WB, whole body; NA, not applicable. There were no significant differences between or within groups for any of the variables.
