Summary of Health-Related Quality of Life (HRQoL) Scores (PROMIS Preference, PROPr) of DISTINCT CMM and SCS Treatments at Six months

	DISTINCT SCS		DISTINCT CMM

Notes: Authors’ calculations from the patient-level data collected using PROMIS-29+2 Profile v2.1 (PROPr) during DISTINCT trial. This table summarizes the Health-Related Quality of Life (HRQoL) metric derived from PROPr. The HRQoL metric ranges from 0 (as bad as dead) to 1 (perfect or ideal health). The mean HRQoL scores show a significant difference in the quality-of-life between patients in DISTINCT SCS vs DISTINCT CMM therapies at six months though the difference is marginal in the baseline between the two groups. ^a p < 0.001.
