bDAS Baseline DASm measurement; Time *bDAS denotes the crossing of a time term with bDAS
-
aThe shapes of the MDAS and SDAS models are defined using 2 time terms each (fractional polynomials). MDAS and SDAS crossed with their common time form (p = –1,) of their respective fractional polynomials (see Additional file 1: Appendix)

bSteroid treatment from 3Â months before each occasion of DASm measurement, i.e., it is a time-varying predictor. Significant results have been bolded
