Text: Compared with cyclophosphamide, vincristine, and prednisone combination regimen, cladribine alone or cladribine and cyclophosphamide combination induced higher probability of overall response (odds ratio [OR] = 4. 0 ; 95 % confidence interval [CI], 1. 7-9, 3 ; P =. 002, and OR = 8. 5 ; 95 % CI, 3. 2-22. 7 ; P <. 0001, respectively), complete remission (OR = 5. 8 ; 95 % CI, 1. 8-18. 5 ; P =. 003 ; and OR = 14 ; 95 % CI, 4. 4-44 ; P <. 0001, respectively), progression-free survival (log-rank test P <. 0001), but not overall survival.
