  • Shows the comorbidities by type and stratified by age group. Comorbidities were substantial in our cohort, with over 78.2% of the over 49s having more than 2. As expected, the number of comorbidities increased with age. The most common comorbidity was hypertension (n=73; 43.2%). The second-most common comorbidity was chronic cardiac heart disease (37, 21.8%), followed by chronic pulmonary disease (n=28; 16.5%), asthma (n=25; 14.8%), and diabetes without complications (25, 15.15%), respectively.
