OR-SDS: participant-rated levels of frequency (F), severity (S), degree of bother (DoB) for 10 symptoms: fatigue, drowsiness, concentration, confusion, nausea, dizziness, constipation, itching, difficulty with urination, retching/vomiting. For each symptom levels of F, S and DoB scored as: frequency (0 to 4:'did not have' to 'almost constantly'), severity (0 to 4:'did not have' to 'very severe'), degree of bother (0 to 5:'did not have' to 'very much'). Mean of F, S and DoB was calculated for each symptom to derive composite scores/multi-domain average (MDA) scores which ranges from 0 to 4.33. Higher MDA=worse symptom. Composite scores for frequency (FCS), severity (SCS), degree of bother, and MDA were calculated as mean of these scores across 10 symptoms and had same ranges as individual scores frequency (0 to 4:'did not have' to 'almost constantly'), severity (0 to 4:'did not have' to 'very severe'), degree of bother (0 to 5:'did not have' to 'very much'); higher scores=more distress
