We aimed to identify if plasma procalcitonin levels on admission are associated with the duration of mechanical ventilation (primary outcome), 28-day mortality, and time to intubation (secondary outcomes) in a cohort of COVID-19 patients requiring mechanical ventilation. In the univariate analysis of our observational cohort study, procalcitonin levels >0.1 ng/ml on admission were associated with prolonged mechanical ventilation in critically ill COVID-19 patients.	./cache/cord-319538-bawzonq1.txt	./txt/cord-319538-bawzonq1.txt
