Incidence of 26 conditions often / previously attributable to post-COVID
Among all patients aged ≥18 years

35.4% of case-patients experienced at least one incident condition
14.6% of controls experienced at least one incident condition
Aged ≥65 years

experiencing an incident condition that might be attributable to previous COVID-19
Conditions affected multiple systems
cardiovascular, pulmonary, hematologic, renal, endocrine, gastrointestinal, musculoskeletal, neurologic, and psychiatric signs and symptoms
Highest risk ratios (RRs)
Acute pulmonary embolism
18 to 64, RR = 2.1
≥65, RR = 2.1
RR = 2.1 and 2.2 among persons aged 18–64 and ≥65 years, respectively) and
Respiratory signs and symptoms
RR = 2.1 in both age groups

The research study
A retrospective matched cohort design

RR for cardiac dysrhythmia
18 to 64, RR = 1.7
≥65, RR = 1.5
Musculoskeletal pain
