At Clinicaltrial they don't say 10% of OS improvement but only the more usual P-Value between the 2 group less than 0.05. Not a little difference.
Primary Outcome Measures: Overall Survival (OS) in LI + CIZ + SOC vs. SOC [ Time Frame: 3 year ] OS will be assessed using Kaplan-Meier life-table and compared using a logrank test and confirmed further with tumor stage location and geographic stratified log rank tests. The unstratified logrank test constitutes the primary analysis. A two-sided p-value of 0.05 or less will be considered statistically significant for comparing the two groups. Interim analyses will be performed throughout the study to assess safety, sample size and futility.
