The relation between changing rheumatoid arthritis disease activity [ΔDAS28(3)-CRP] and changing glycosylation. Distinction is made between the timeframes to assess responder status (the change between first and third trimester; top row) and flare status (the change between third trimester and 12 weeks postpartum; bottom row). ΔA2S0G, the change in galactosylation per antenna of diantennary non-sialylated species; ΔA2FS0G, the change in galactosylation of diantennary fucosylated non-sialylated species; ΔA3FGS, the change in sialylation per galactose of triantennary fucosylated species. The significance of the models (p) arrives from linear regression, the correlation coefficients (r) from Pearson correlation.
