Expression of TCR zeta and clinical features in SLE

	% expression of TCR ζ
Clinical features	(+)	(−)	P-value
Butterfly rash	32·7 ± 28·7	71·4 ± 14·9	0·005*
Discoid rash	25·1 ± 1·7	46·1 ± 32·2	0·550
Photosensitivity	49·0 ± 25·8	39·3 ± 34·4	0·283
Oral ulcers	33·1 ± 35·6	47·1 ± 29·3	0·485
Polyarthritis	46·1 ± 31·4	25·0 ± 22·6	0·356
Serositis	29·6 ± 25·6	48·5 ± 31·8	0·280
CNS	36·7	43·6 ± 31·6	0·203
Renal	37·9 ± 32·2	46·3 ± 30·9	0·833
Vasculitis	27·4 ± 26·0	50·7 ± 30·9	0·553
Anti-dsDNA	36·2 ± 32·5	51·7 ± 28·1	0·100
Anti-RNP	41·7 ± 30·4	44·3 ± 32·4	0·100
Anti-Sm	34·7 ± 39·4	45·2 ± 29·7	0·853
Anti-SS-A	45·7 ± 31·6	41·3 ± 31·5	0·747
Antiphospholipid	16·5 ± 17·8	53·3 ± 28·9	0·009*

Results were expressed as mean ± s.d. Expression of TCRζ was determined by densitometric analysis on the TCR ζ bands, and compared between those with or without the clinical feature.
