Figure 2.

Kendall–Tau matrix - SLEDAI, m-SLEDAI (Mexican -SLEDAI/clinical SLEDAI) are strongly associated with higher basal and ΔNBT (Del OD) values but not with stimulated NBT values.

High dose steroid: >−10 mg prednisolone or equivalent/day.

Other medications include any steroid sparing immunosuppressive – azathioprine, cyclophosphamide, mycophenolate, etc.

The matrix represents correlation coefficients of pairwise variables.

The red background depicts inverse association, while the green background depicts positive association.
