Machine learning model of anti-dsDNA IgG and total IgG. (a)-(h) showed the predicted glycoform value (predicted value) and true value (data from our study) of anti-dsDNA IgG1 and total IgG1. The blue line represented the predicted value, and the red line represented the real value. SSE of each sample was used to compare the difference between the predicted value and the true value. (a)-(d) suggested that anti-dsDNA IgG1 had a better performance than that of total IgG1 with smaller SSE.

Abbreviations: IgG: Immunoglobulin; SLEDAI: systemic lupus erythematosus disease activity index; SLE: Systemic Lupus Erythematosus; SSE: Standardised square error.
