3.2 Comorbidities, clinical manifestations and laboratory
parameters
As presented in Table 1, the difference in diabetes prevalence between
the two groups was statistically significant (P < 0.05).
However, the difference in HTN, CHD, lung malignancy, and other lung
diseases was not statistically significant (P > 0.05). As
shown in Table 2, no statistically significant difference in cough,
fever, chest pain, tightness, and breathlessness was found between the
two groups (P > 0.05). Moreover, no statistically
significant difference in the FIB index was seen between the two groups
(P > 0.05). However, significantly increased NLR and CRP,
and significantly decreased ALB were observed in the heavy group
(P < 0.05) as compared to the general group (Table 3).
