At the 10% level of significance, the between group difference was 43% (P = 0.023), 33% (P = 0.067) and 47% (P = 0.004) smaller for T cells, memory B cells and plasmablasts respectively compared to monocytes; at the 20% level of significance there was evidence suggestive of overall variation between cell subtypes in the SLE:HC IFN Score B expression ratio (Χ2(5) = 8.9, P = 0.114). Here, IFNA1 is linked to systemic lupus erythematosus.
