Flowchart of study population, showing (A) cohorts and (B) further details of the systematic screening cohort.
1D-dimer cut-off ≥ 500 ug/L if ≥ 1 YEARS items; D-dimer cut-off is increased to 1000 ug/L if 0 YEARS items. ED, emergency department; CTPA; computed tomography pulmonary angiogram; PE, pulmonary embolism.

Baseline characteristics.
Fig 2.
Scatter plot of the D-dimer levels in patients who underwent CTPA according to the YEARS algorithm, in whom PE was ruled out and confirmed, on a base-2 log scale.
Each dot represents one patient. Horizontal lines show the median, error bars show the interquartile range. PE, pulmonary embolism.

Chart of the total number of ED patients with COVID-19 in whom pulmonary embolism was confirmed (left axis, represented as the bar graph) and the proportion of confirmed PE among ED patients with COVID-19 (right axis, shown with the line graph), plotted for each month.
ED, emergency department; PE, pulmonary embolism.
