At baseline, the most commonly used conventional DMARDs were methotrexate (TAK=12, GCA=10) and mycophenolate mofetil (TAK=6, GCA=0). At follow up, the most commonly used conventional DMARDs were methotrexate (TAK=14, GCA=3) and mycophenolate mofetil (TAK=6, GCA=1).
At baseline, and the most commonly used biologic DMARDs were tumor necrosis factor inhibitors (TAK=6, GCA=0) or tocilizumab (TAK=2, GCA=1). At follow up, the most commonly used biologic DMARDs were tumor necrosis factor inhibitors (TAK=10, GCA=0) or tocilizumab (TAK=9, GCA=20).
