Results:
During the study period, 161 and 114 patients were followed in the
Lop/Dox cohort and the Others cohort, respectively. The Lop/Dox cohort
was older and had lower O2 saturation at admission. The
proportion of patients needing intubation did not differ between the
cohorts (Lop/Dox, 15∙5%; Others, 16∙7%). The overall fatality rate
likewise did not differ (12∙4%) in Lop/Dox and 8∙7% in the Others
cohort). Older age and elapsed time between the onset of symptoms and
hospitalization, O2 saturation at admission, and the
lymphocyte to white blood cell ratio were independent risk factors for
poor outcomes of the illness.
