FIGURE 1.

Timelines of disease state and sample timing. We analyzed plasma samples drawn at t1 and t2 for COVID‐19/PE+patients. COVID‐19/PE‐ and influenza‐associated ARDS patients were matched for positive end‐expiratory pressure (PEEP), fraction of inspired oxygen (FiO2), cardiovascular sequential organ failure assessment (cSOFA) score, and number of days on mechanical ventilation at t1. Timepoint t2 in controls was determined pairwise, using an interval between t1 and t2 identical to that observed in the COVID‐19/PE+case (not shown in this figure). PE+ = patients who developed pulmonary embolism, PE‐ = patients who did not develop pulmonary embolism
