Proportion of patients in ultrasound remission, according to different ultrasound remission definitions as well as different clinical remission criteria
| Patients in DAS28CRP-remission | ||||
| All patients (n = 87) | csDMARD group (n = 45) | bDMARD group (n = 42) | Difference between treatment groups (p value) | |
| Ultrasound strict remission | 6 (7%) | 0 (0%) | 6 (14%) | 0.01 |
| Ultrasound semi-strict remission | 32 (37%) | 15 (33%) | 17 (40%) | 0.50 |
| Ultrasound Doppler remission | 49 (56%) | 26 (58%) | 23 (55%) | 0.78 |
| Patients in ACR-EULAR Boolean-remission* | ||||
| All patients (n = 67) | csDMARD group (n = 34) | bDMARD group (n = 33) | Difference between treatment groups (p value) | |

Values are given as number of patients and percentage. Comparison between groups by Pearson chi-square with p < 0.05 considered significant
Ultrasound strict remission no joints with GS score > 0 and Doppler score > 0, ultrasound semi-strict remission no joints with GS score > 1 and Doppler score > 0, ultrasound Doppler remission no joints with Doppler score > 0. csDMARD conventional synthetic disease-modifying anti-rheumatic drug, bDMARD biological disease-modifying anti-rheumatic drug, GS grey scale
*Patients in ACR-EULAR Boolean-remission are identical to patients in CDAI-remission
