The median duration from symptom onset to treatment initiation was 3.6 months. Baseline disease activity was moderate, with mean Simplified Disease Activity Index and Clinical Disease Activity Index values of 21.2 and 19.5, respectively. All patients initiated treatment with conventional synthetic disease-modifying antirheumatic drugs (DMARDs), and treatment was managed according to a treat-to-target strategy. At 1 year after treatment initiation, 110 patients (41.5%) received biologic or targeted synthetic DMARDs. Concurrently, 215 patients (81.1%) maintained radiographic remission of the hands and wrists, defined as a change in the modified total Sharp score (mTSS) of the hand and wrist (\u0394hand\/wrist mTSS) of \u2264 0.5\/year. Multivariable logistic regression analysis showed no significant association between clinical factors, including disease activity indices, and radiographic progression. The presence of power Doppler (PD) signals penetrating into bone erosions was the only independent factor associated with lower odds of maintained structural remission (odds ratio 0.20; 95% CI
