*Symptom was indicated as “yes” if the subject reported the symptom as moderate or severe at least 50% of the time during the two week baseline period. Otherwise, symptom was reported as “no” for that individual.

†Mean symptom severity score over the two week baseline period was used in the model, with the OR corresponding to a 1 point average increase in severity for that symptom.

‡Each symptom was adjusted for age, sex, body mass index, and centre type.

OR (95% CI), odds ratio (95% confidence interval).
