Correlation between type 1 IFN signature score and leukocyte infiltration index in myositis. A significant linear correlation is displayed in the scatter plot between type 1 IFN index and leukocyte infiltration index. Data points are colored by the sample type; color key is displayed in the upper right corner of the plot. The regression line (R2=0.41, p<0.001) is denoted by the black dotted line and 95% confidence interval is outlined by the red dotted line and gray shaded background. The subject identifiers of the four outliers are labeled. When excluding the four outliers, the R-squared value in the regression analysis escalates from 0.41 to 0.91.
