Longitudinal follow‐up of anti‐Ro60^low and anti‐Ro60^high groups

	Anti‐Ro60low (n = 25)	Anti‐Ro60high (n = 25)	P‐value
Mean follow‐up period (years ± SD)	2·15 ± 1·20	2·68 ± 1·69	0·207
Additional LIB specificities at baseline (mean ± SD)	0·64 ± 1·04	1·08 ± 1·19	0·170
Loss/no change/gain of additional LIB specificities by end of follow‐up (n)	3/21/1	4/14/6	0·307
Additional LIB specificities by end of follow‐up (mean ± SD)	0·52 ± 0·92*	1·24 ± 1·01*	0·011
Decreased/same/increased anti‐Ro60 intensity group by end of follow‐up (n)	4/18/3	8/16/1	0·294

^* P > 0·05 compared to baseline within the same anti‐Ro60 subset.

Bold value represents significant P < 0·05.

SD = standard deviation; LIB = line immunoblot assay.
