NBL1 and coronary artery disorder: In addition, a very weak to weak association was observed between NBL1-Ab level and age (ρ = 0.13, p = 0.042, Fig 2A), mean SpO2 (ρ = −0.28, p = 0.010, Fig 2E) and arousal index (ρ = 0.28, p = 0.012, Fig 2F), whereas a significantly higher NBL1-Ab level was observed in patients with CAD than in those without CAD (p = 0.015, Fig 2K).
