Correlation between the physical symptom questions* from the prospective clinical monitoring questionnaire and the Physical Component Scale of the retrospective health-related quality of life (HRQoL) for the four time periods
| Time | Slope (SD)† | OR‡ | 95% CI | p Value | OR§ | 95% CI | p Value |
|---|---|---|---|---|---|---|---|
| Pretrial | 2.67 (13.0)† | 1.46 | (1.01 to 2.11) | 0.043 | 1.00 | ||
| 4 weeks | 8.07 (18.6) | 3.18 | (2.11 to 4.80) | <0.001 | 2.18 | (1.44 to 3.28) | <0.001 |
| Delivery | 4.91 (12.2) | 2.14 | (1.37 to 3.35) | <0.001 | 1.46 | (0.94 to 2.29) | 0.10 |

*The scores for four questions were combined as a single index: Do you have energy? Do you feel fatigued or sleepy? Do you feel light-headed (dizzy)? Do you feel short of breath? Responses: Not at all; A little of the time; Sometimes; Most of the time; Always.
†The slope (SD) of the association between the physical symptom questions from the clinical monitoring questionnaire and the Physical Component Scale of the HRQoL for the four time periods was estimated by repeated measures general linear modelling for illustrative purposes only (mean index score at pretrial was 74.3 of 100).
‡The strength of the absolute association at each timepoint was compared to the pretrial timepoint and was estimated using repeated measures ordered logistic regression and expressed as OR (95% CIs; p values).
§The strength of the relative association at the other timepoints was compared to the pretrial timepoint and was estimated using repeated measures ordered logistic regression and expressed as OR (95% CIs; p values).
