The table includes (from left to appropriate): protein IDs (Uniprot accession quantity), gen name and protein description. Table S6. Proteins highlighted by Random Forest model for classifying CACs incubated with serum samples of asymptomatic donors (PCR + , IgG + and Damaging). The evaluation test mode applied fivefold crossvalidation. The table includes (from left to suitable): Protein IDs (Uniprot accession quantity), gen name and protein description.

Author contributions RML made and managed the logistics of recruitment, collection, stratifica tion and samples storage. MPMN, VMB and IGDLT, patient recruitment and determination of patient infection by rtPCR. LBC, SEA and MRT performed ELISA assays to confirm the patients’ infective stage (IgG/IgM). SEA and LBC performed proteomic evaluation of serum and CACs respectively. LBC performed functional/biological analyses, and made the figures and tables. LBC and MCD evaluated the final information, wrote the principle draft, edited and revised the manuscript. RML, JAM, EB and MCD conceptualized the project, and revised the manuscript, offering final recommendations. All authors have study and approved the final manuscript.

The table includes (from left to correct): Quantity of serum sample, PCR test for virus detection results, ELISA test for IgM and IgG detection outcomes. Table S2. Quantitative analysis of proteins differentially expressed in serum samples (vs Neg). The table contains (from left to ideal): Protein IDs (Uniprot accession number), protein description, PCR + / Neg ratio, PCR + /Neg pvalue, IgG + /Neg ratio and IgG + /Neg pvalue. Overexpressed values are indicated in red (thinking of upregulated ratio 1.five) and underexpressed values in green (HPV E6 Proteins web downregulated ratio 0.six). The table shows the significant values for no less than one of many comparisons (pvalue 0.05 as differentially significant). Table S3.
