Unless indicated otherwise, values are presented as No. (%) of patients. The N value is the number of unique patients in the cohort or specified period (there is an overlap of patients in the prepandemic and pandemic periods).
Some patients had multiple hematologic neoplasms and thus had different ages at initial diagnosis depending on the disease. These patients were counted multiple times for this characteristic, resulting in a total N value for the characteristic that is greater than that for the cohort.
Specific race and ethnicity categories with lower representation in the US population were grouped as other for deidentification purposes and may include American Indian or Alaska Native, Hawaiian or Pacific Islander, or multiple races and ethnicities.
