Using group\u2010based trajectory models (GBTM), we modelled symptoms (mean total numbers and proportion with four specific complaints), including age, sex, BMI and timing of infection as covariates. In a multivariable linear mixed\u2010effects model, we assessed the association between symptom trajectories and repeated B\u2010IPQ scores.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 292 participants (42% female; median age 51 [IQR\u2009=\u200936\u201362]), four trajectories were identified, ranging from Trajectory 4 (8.9%; 6\u2009+\u2009symptoms) to Trajectory 1 (24.8%; no symptoms). The occurrence of fatigue and myalgia increased among 23% and 12% of participants, respectively.
