Figure 2

Cycle threshold of the RT-PCR for SARS-CoV-2 in BAL fluid by the interval of time from onset of symptoms at time of BAL procedure in 13 SARS-CoV-2-positive patients. The Pearson correlation coefficient was 0.8, . Dots and triangle represent the patients alive and dead, respectively, 4 weeks after the BAL. Red markers represent the patients admitted to the ICU. Abbreviations: BAL—bronchoalveolar lavage; RT-PCR—reverse transcriptase polymerase chain reaction.
