Validation of the expression of a diagnostic biomarker in the dataset for the validation group GSE20881. A (LCN2); B (NAT8). On a number axis, the box plot's upper and lower edges represent the upper quartile and lower quartile, respectively, enabling observation of the quartile distance to determine if normal value distribution is concentrated or dispersed. The median is represented by a thickened line in the middle of the box plot
