The fecal meta-proteome distinguishes individuals with islet autoimmunity and new-onset (NO) patients from control subjects. A: sPLS-DA of all human and microbial proteins comparing NO, seropositive (SP), and combined healthy control and seronegative (CO/SN) groups. B: Component 1 contributing variables. Red text, human proteins; black text, microbial proteins; 158742018-stool1_revised_scaffold9355_1_gene110855 abbreviated as gene11085. C: Log-normalized intensity of significant proteins comparing NO, SP, and CO/SN subject groups by one-way ANOVA (adjusted P < 0.05). Data are mean ± SEM. D and E: sPLS-DA of human and microbial proteins, respectively, comparing NO, SP, and CO/SN subject groups. A PERMANOVA comparing the three groups is shown. *P < 0.05; **P < 0.01; ***P < 0.001.
