State 0 means that the patient did not report the symptom. State 1 means that the patient did report the symptom. For example, 0 → 0 means a transition from state 0 (symptom not reported at baseline) to state 0 (symptom not reported after 1 year). 0 → 1 means that the patient did not report the symptom at baseline but did report it at the 1-year follow-up, and so on (95% confidence intervals).

a

Symptoms reported to be at least a little bothersome (Severity level I).

b

Lyme borreliosis-related symptoms, not in the original SHC questionnaire.

c

The confidence interval is not given because of the small numbers reporting this symptom.
