Proportion of NKT cells in first-degree relatives of lupus patients, stratified by the presence of autoimmune disease and ANAs

		Self-reported autoimmune disease		Confirmed autoimmune disease
		No	Yes	No	Yes
ANA status	Negative	0.089 ± 0.237 (0.030)	0.079 ± 0.198 (0.017)	0.092 ± 0.234 (0.035)	0.039 ± 0.054 (0.016)
	Positive	0.040 ± 0.048 (0.022)	0.020 ± 0.029 (0.009)	0.036 ± 0.046 (0.019)	0.016 ± 0.029 (0.008)

Shown is the proportion of natural killer (NK)T cells mean ± standard deviation (median) for each group. ANA, anti-nuclear antibody.
