Results of the Cox proportional hazards model

End pointFactorHazard ratio (95% confidence interval)PSelection frequency (%)
EFSβ2-Microglobulin1.13 (1.03-1.23)0.0177.5
Amplitude A1.62 (1.02-2.58)0.0264.5
OASβ2-Microglobulin1.20 (1.08-1.33)<0.00177.5
  • NOTE: Hazard ratios and confidence intervals are computed for a 1-unit increment in β2-microglobulin and a 0.5-unit increment in amplitude A.

    Abbreviations: EFS, event-free survival; OAS, overall survival.
