B: regression coefficient in the equation which predicts the grade of the lesion considering to both sMICA and NKG2D expression as independent variables; SEM for B: standard error for the regression coefficients; Beta: standardized regression coefficient which determines the actual weight of the regression coefficient if all variables are expressed in standard units; t: t-test value for the regression coefficient; sig: p value (R² = 0.467; p < 0.001).
