The model including age > 65 years, male sex, cardiovascular disease, dyspnoea and at least three abnormal blood parameters among CRP (> 80 U/L), ALT (> 40 U/L), NLR (> 4.5), LDH (> 250 U/L), and CK (> 80 U/L) shows fair discrimination ability (AUC 0.73). Here, GPT is linked to cardiovascular disorder.
