  1. Radiographic progression was assessed by annual change in Sharp/van der Heijde score (SHS) during follow-up period. RRP (rapid radiographic progression) was defined as 5 or more unit change in SHS per year. Complete sustained remission was defined as maintain rate of 100%. Nearly sustained remission was defined as maintain rate of 50% and more. Incomplete sustained remission was defined as maintain rate of less than 50%. None remission was defined as maintain rate of 0%
