TNFRII 196R allele and progression of the structural damage over the 1-yr follow-up

	Whole cohort			RA patients
	TNFRII 196R allele		P	TNFRII 196R allele		P
	Absent (n = 132)	Present (n = 106)		Absent (n = 76)	Present (n = 80)
Baseline radiographic score	2.00 (0–24)	2.50 (0–38)	0.34	2.00 (0–21)	3.00 (0–38)	0.42
1-year radiographic score	2.00 (0–36)	3.00 (0–38)	0.24	2.00 (0–36)	3.00 (0–38)	0.27
Radiographic score progression	0.00 (-1 to +15)	0.00 (0–17)	0.98	0.00 (-1 to +15)	0.00 (0–17)	0.92

The total radiographic score, calculated in accordance with the van der Heijde modified Sharp method, was used to quantify the progression of the structural damage for the whole cohort and for rheumatoid arthritis (RA) patients, whether or not they carried the 196R allele. Values are expressed as median (interquartile range).
