Clusterin concentrations did not differ significantly between male and female patients (p = 0.727) (Figure 2A), patients aged up to 64 years or older (p = 0.271) (Figure 2B), or patients with or without certain comorbidities, such as: coronary artery disease (p = 0.229) (Figure 2C), hypertension (p = 0.162) (Figure 2D), chronic obstructive pulmonary disease (COPD) (p = 0.063) (Figure 2E), or liver cirrhosis (p = 0.690) (Figure 2F). Here, CLU is linked to cirrhosis of liver.
