| Zoledronic acid (n=555) | Clodronic acid (n=556) | p value | Zoledronic acid (n=426) | Clodronic acid (n=423) | p value | |
| CR, VGPR, or PR | 432 (78%) | 422 (76%) | 0·43 | 215 (50%) | 195 (46%) | 0·18 | 
| CR or VGPR* | 200 (36%) | 193 (35%) | 0·63 | 85 (20%) | 60 (14%) | 0·018 | 
| CR* | 78 (14%) | 69 (12%) | 0·42 | 39 (9%) | 27 (6%) | 0·13 | 
CR=complete response. PR=partial response. VGPR=very good partial response.
