3.5 CD161+CD56+NK cells proportion was negatively correlated
with disease activity in pSS patients
We subsequently analyzed the correlations between CD161+CD56+NK cells
proportion and laboratory features and disease activity index in pSS
patients
(Table 3).It was found that a positive correlation was verified between
CD161+CD56+NK cells proportion and C4(r=0.4205, P =0.0289,Table 3,
Fig.4J), and CD161+CD56+NK cells proportion was negatively correlated
with WBC(r=-0.3893,P =0.0369,Table
3,Fig.4A),IgA(r=-0.4594,P =0.0093,Table
3,Fig.4B),IgM(r=-0.4047,P =0.0294,Table 3,Fig.4C),
IgG(r=-0.4968,P =0.0159,Table 3,Fig.4D), ESSDAI(r=-0.3624,P =0.0451,Table 3,Fig.4E) and ESSPRI(r=-0.4863,P =0.0055,Table 3,Fig.4F).However,there was no significant
difference of correlations between
CD161+CD56+NK cells and ESR, serum globulin and C3(Table 3).
