  1. Estimated hazard ratios (HR) with 95% confidence intervals (CI) are provided. The subgroups of female, stage IIIC, PS = 1, ulcerated, in-transit without lymph node involvement demonstrated significant improvement in OS and/or RFS with ipi3 versus HDI. Female gender was significant for both OS and RFS
