Protein abundance patterns differentiate proteins identified and recovered by both collection methods.

<p>the Weck-Cel cervical sponge method (CER) and the cervicovaginal lavage method (CVL) (Proteins shown (121) were identified as differentially abundant by one-way ANOVA (p<0.05)). Clustering of proteins was generated by unsupervised centroid linkage hierarchical clustering using the Pearson correlation coefficient as the distance metric. Protein abundance levels are shown in colour, with red indicating overabundant proteins and green indicating underabundant proteins compared to the median of all samples for either collection method.
