Houston et al. [52]2014Retrospective cohort3929 were on prednisone or deflazacortAlendronate PO12 years old
(no range given)
-score trended up at the hip with alendronate, but it is not statistically significant10 did not receive alendronate, varying dosages of alendronate used

Sbrocchi et al. [53]2012Retrospective observational7All but 1 were reported as prednisone equivalentsPamidronate IV 9 mg/kg/year or zoledronic acid IV 0.1 mg/kg/year11.6 years old (range: 8.5–14.3 years old)Improved back pain and stabilization to improvement in vertebral height ratios for the previously fractured vertebraeOnly patients with vertebral fractures were included in the study

Gordon et al. [54]2011Retrospective observational445 prednisone only; 13 changed from prednisone to deflazacort; 26 deflazacort only11 used pamidronate only; 1 changed from pamidronate to alendronate; 3 alendronate only; 1 clodronate only12.5 years old (range: 7–23 years old)Survival curve showed improvement in survival rate (, log-rank test); also, possible therapy duration effect could be present , log-rank test)Pamidronate was IV; alendronate was PO; clodronate was PO

Atance et al. [55] 2011Case reports32 on deflazacortAlendronate 10 mg daily PO11.4 years old (range: 8.1–15.8 years old)Reduced back pain and improved BMDOnly 3 patients were reported
