Table 4 Proportion of NKT cells in first-degree relatives of lupus patients, stratified by the presence of autoimmune disease and ANAs

From: Reduced proportions of natural killer T cells are present in the relatives of lupus patients and are associated with autoimmunity

   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)
