Two-year trajectories of COVID-19 symptoms and their association with illness perception: A prospective cohort study in Amsterdam, the Netherlands 6 201 Supplementary Table S9. Association between month 1 total B-IPQ score and group-based trajectory group, adjusted for age, sex and timing of SARS-CoV-2 infection 95% CI aOR Lower limit Upper limit p-value B-IPQ, total score (per 10 point increase) 2.35 1.85 2.99 <0.001 Age, years (per 10 year increase) 1.00 0.84 1.20 0.966 Sex Male Ref. Female 3.14 1.79 5.53 <0.001 Timing of infection First wave Ref. Subsequent waves 4.07 1.83 9.04 0.001 B-IPQ = Brief Illness Perception Questionnaire; CI= confidence interval. aOR= adjusted odds ratio. According to Likelihood Ratio Tests, BMI category and initial COVID-19 severity did not lead to a significantly better fit and were therefore excluded. Timing of SARS-CoV-2 infection defined as: first wave (up to 1 June 2020) and subsequent waves (on or after 1 June 2020). Trajectory group membership was based on the maximum a posteriori probability of belonging to that group. The model met the proportional odds assumption.
