a
P<0.05 vs. AECOPD group;
b
P<0.05 vs. AECOPD/PE group;
c
P<0.05 vs. AECOPD/PE group. The determined P-value for each variable in the table were comparisons between all three groups. AECOPD, acute exacerbation of chronic obstructive pulmonary disease; PE, pulmonary embolism; AF, atrial fibrillation; CTD, connective tissue disease; WBC, white blood cell; LDL, low-density lipoprotein; HDL, high-density lipoprotein; TG, triglycerides; TC, total cholesterol.
