Fig. 3: Risk differences of self-reported health problems with new onset between the test date and until 6–12 months after, comparing SARS-CoV-2 test-positive and test-negative participants.

Note: Bars indicate risk differences (center) with 95% confidence intervals (length of error bars) adjusted for age, sex, comorbidities, obesity, healthcare occupation, and time after testing (in months). For health problems with onset between the test date and until 6–12 months after the test date, all test negatives no matter of the indication for testing are used as control population. All symptom questions were mandatory, so for all lines the proportions are based on 61,002 test-positive and 91,878 test-negative individuals. An individual could only participate in the study once, as either test-positive or test negative.
