Association between response rate (≥60.0% is reference) and QOL scores from multiple linear regression analyses. Analyses adjusted for type of SPC service (hospice vs. palliative care team) and with random effect of patient id and SPC service. CL = confidence limit, MD = mean difference. For the symptom scales, a negative MD means that the < 60.0% response rate groups have lower symptom scores than the ≥60.0% response rate group. For functional and QOL scales, a positive MD means that the < 60.0% response rate groups have higher functioning/QOL than the ≥60.0% response rate group. Blue dotted lines show the minimum level for clinically relevant mean differences. *Overall p-value for the association between response rate and scale score was < 0.05. **P-value for difference in symptom score between the ≥60.0% response rate group and one of the lower response rate groups was < 0.05
