Results of univariate Weibull hazards model. Statistical significance is indicated if the 95%CI hazard ratio does not encroach upon a risk ratio of 1.0; the more towards red color indicates increased risk of endpoint occurrence, while the more towards green color indicates risk reduction. OS, LC, LRC, FDD, RFS, EFS, DSS, and NCCSS proportional hazards were assessed for all patients (n=221). LEDFS, LxFS, and FFL hazard ratios (labeled with a “*”) were calculated only for those patients dispositioned to larynx preservation initially (n=60).
