Validation results
The basic characteristics of included patients at admission are shown inTable 3 . A total of 148 patients were included in this study.
Severe cases accounted for 19.6%. The most common symptoms at admission
were fever (81.76%) and cough (61.49%). The less common symptoms were
muscle pain (20.27%), fatigue (17.57%) and sore throat (17.57%). The
respiratory rate was accelerated on admission in severe patients
compared with that in non-severe patients. The proportion of fever in
the severe group (96.55%) was higher than that in the non-severe group
(78.15%) (p=0.021), but the incidence of gastrointestinal symptoms such
as diarrhea and abdominal pain was lower.
