Figure 4. Cumulative hazard of the risk of in‐hospital procedures overall among intermediate and high‐severity pulmonary embolisms in the matched cohort together (A) and separately (B and C).

Cumulative hazard curves demonstrate the risk of any intervention in the combined high‐ and intermediate severity pulmonary embolisms (A), intermediate severity only (B), and high severity only (C) adjusting for the competing risk of mortality, clustering by hospital size, and censoring for hospital discharge in the matched cohort (risk tables). A, Black (light gray) patients hospitalized with intermediate or high‐severity pulmonary embolism have a lower relative risk of undergoing any interventions when compared with White (dark gray) patients. The association between receipt of therapy and race differed between intermediate and high‐severity subgroups (P value of interaction, <0.001; B, Risk of intervention for intermediate severity pulmonary embolism. C, Risk of intervention for high‐severity pulmonary embolism).
