High frequencies of Ki67+ natural killer (NK) cells are associated with increased disease severity. (a) Linear regression analysis of the frequency of Ki67+ NK cells and Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) (n = 174). (b) Scatter‐plot of binned healthy donor (HD) and SLE patients according to disease severity comparing the frequency of Ki67+ NK cells. Middle bar denotes median; surrounding bars denote first and second interquartile ranges. Statistical analysis performed using Spearman’s ranked correlation and Kruskal–Wallis test. ***P < 0·0001.
