Accession	Description	Coverage [%]	Abundance Ratio: (AP)/(Control)^*a	P value^*b	Correlation coefficient^*c	P value^*d
Q86SG5	Protein S100-A7A	69	6.51	0.065	− 0.771	0.072
P41567	eukaryotic translation initiation factor 1	62	3.03	0.093	− 0.829	0.042
P48594	Serpin B4	67	2.6	0.065	− 0.771	0.072
O75594	peptidoglycan recognition protein 1	53	1.23	0.093	− 0.829	0.042

The proteins were detected in all 12 samples with a coverage of > 50%
^*aAbundance Ratio was calculated using Proteome Discoverer software version 2.2
^*bP values were calculated by Mann–Whitney U test using the protein abundance (AP vs. Control)
^*cCorrelation coefficients between days post-onset and protein abundance in the AP group
^*dP values were calculated by Spearman’s test
