The evidence shows a 38.4% overall survival rate with stark gender differences (109/577 males vs 233/314 females survived). I should examine class-based survival patterns, as the 'women and children first' protocol might interact with socioeconomic factors in unexpected ways. Let me check survival rates by passenger class.",
