CI indicates confidence interval; and IPI, International Prognostic Index.
Variables with greatest significance in Cox proportional hazards model analysis. The Cox model included all individual IPI prognostic factors, combined high IPI risk categories (3-5) versus low modified IPI risk categories (0-2), and marker data where available.
