| EQ-5D-5L Health Profile Grouping, %a | 10-kHz High-Frequency SCS | Comparator SCSb | Combined |
|---|---|---|---|
| Better | 79 | 79 | 79 |
| Equal | 0 | 0 | 0 |
| Mixed | 18 | 9 | 14 |
| Worse | 3 | 12 | 7 |
Abbreviation: SCS, spinal cord stimulation.
a
EQ-5D-5L health profile groupings: better (at least 1 dimension better and no worse in any other); equal (health state exactly the same); mixed (better and worse on at least one dimension); worse (at least one dimension is worse and is no better on any other).
b
Comparator SCS protocols included low-frequency, burst, and 1.2–1.5 kHz moderate-frequency.
