Relationship between the clinical types and LCA-derived subgroups

OR odds ratio, CI confidence, LCA latent class analysis

Model 1: we did not adjust other co-variants

Model 2: we adjusted age, sex, and body mass index

Model 3: we further adjusted outcomes, fever, hypertension, lymphocyte count, C-reactive protein
