Patient characteristics and symptom clusters. (a) Time from symptom onset to hospital admission. Data are presented as counts in singleday bins. Vertical dashed lines represent the median time (days). (b) Co-morbidities by symptom cluster. Percentage of individuals with co-morbidity at time of admission. (c) Association between patient characteristics and symptom cluster membership. Multinomial regression, presented as relative risk ratio (95% confidence interval). Core symptoms chosen as reference cluster. The age group 60-80 years serves as the reference group for age.
