Retrospective cohort study examining the clinical features and risk factors for the development of COVID-19

Abstract

Objective: A global epidemic of coronavirus disease 2019 (COVID 19) has been occurring since December 2019 from Wuhan, China. At Jiangan Fangcang Shelter Hospital in Wuhan, China, a retrospective cohort research was carried out to compile the clinical features of COVID-19 patients and investigate the risk factors influencing the length of the illness.

Methods: A retrospective analysis of the clinical features of 409 COVID-19 patients was conducted. We outline each patient's clinical features and the distribution of their transfer or discharge times. After that, we used univariate and multivariate Cox regression analysis to find possible risk variables for either mortality or the progression of COVID-19 from non-severe to severe.
