Objectives Several physiological abnormalities that develop during COVID-19 are
associated with increased mortality. In the present study, we aimed to develop a clinical risk …

Objective To analyse the accuracy of commonly used risk scores (PSI and CURB‐65) in
predicting mortality and need for ICU admission in Covid‐19. Material and methods …

Backgrounds Validated tools for predicting individual in-hospital mortality of COVID-19 are

Most of the existing prediction models for COVID-19 lack validation, are inadequately
reported or are at high risk of bias, a reason which has led to discourage their use. Few …

Patients hospitalised with COVID-19 have a high mortality. Identification of patients at
increased risk of adverse outcome would be important, to allow closer observation and …
