Epidemiological Summary Insights
- Pediatric Peak (2-10 years): High frequency due to fragile finger-accessible anterior capillaries (Kiesselbach's plexus) and frequent URIs.
- Elderly Peak (50-80 years): Driven by arterial sclerosis, hypertension, thinner mucosa, and widespread anticoagulant therapy.
- The ~40% Baseline: Approximately 39.8% of individuals retain sufficient vascular elastic compliance and mucosal moisture to never cross the rupture shear threshold across 80 lifetime years.
