The nomogram model for predicting the severity of COVID-19 was based on five clinico-radiological features including MOICT, age, CD4+ T cell count, serum LDH, and CRP. COVID-19, coronavirus disease 2019; MOICT, the mass of infection in the whole lung; CD4, cluster of differentiation 4; LDH, lactate dehydrogenase; CRP, C-reactive protein.
