Change in SLEDAI-2K and SRI-50 scores in patients who improved in association with the external construct, the Likert scale (LS) score.
| Likert Scale | Δ SLEDAI-2K | Δ SRI-50 |
|---|---|---|
| LS 4, n = 15 | –0.33 ± 1.99 | –0.47 ± 2.07 |
| LS 5, n = 20 | –0.95 ± 2.68 | –1.50 ± 2.72 |
| LS 6, n = 20 | –2.40 ± 2.60 | –3.80 ± 2.95 |
| LS 7, n = 7 | –4.29 ± 4.07 | –5.14 ± 3.18 |
| r1 and r2 | 0.39 | 0.48 |
| p | 0.02 | < 0.0001 |
| Improvement (n = 62) | ||
| LS 4–5 | –0.69 ± 2.40 | –1.06 ± 2.48 |
| LS ≥ 6 | –2.89 ± 3.09 | –4.15 ± 3.01 |
| t test | 0.003 | < 0.0001 |
LS 4: unchanged; LS 5: mildly improved; LS 6: moderately improved, i.e., ≥ 50%; LS7: much improved, i.e., ≥ 50%.
