We retrospectively examined whether clinical and laboratory findings on admission could predict COVID-19 prognosis. Among various factors associated with COVID-19 severity, our results indicated that the real-time reverse transcription-polymerase chain reaction (RT-PCR) threshold cycle (Ct) values for severe acute respiratory syndrome coronavirus 2 were the most useful predictor of COVID-19 prognosis. shows the summary of the clinical characteristics and laboratory findings of the 19 69 patients on admission. The median age was 69 years, and 16% of patients were female. Hypertension and diabetes were present in 42% and 21% of patients, respectively. Most patients 71 had fever (63%) and dyspnea (68%). Lymphopenia, elevated neutrophil-to-lymphocyte ratio Next, we investigated which findings were different between the "critical illness" and "non- Labor and Welfare.
