In the SS group, there were no significant differences in the number of patients treated with a muscarinic M3 receptor agonist (pilocarpine or cevimeline) and corticosteroids or immunosuppressants at baseline (12/23 [52%] and 6/23 [26%], respectively) and at re-evaluation (14/23 [61%] and 8/23 [35%], respectively) (p = 0.766 and p = 0.749, respectively). Here, CHRM3 is linked to synovial sarcoma.
