Fig. 1

Microbiota of the post-operative maxillary sinus in repeated samples from 35 subjects (patients receiving antibiotics within 8 weeks are noted with red asterisk). In this heatmap visualization, the subjects are divided into groups based on the presence or absence of maxillary sinusitis at the time of sample collection. Each column represents one sample, and subject numbers are listed under paired samples from the same individual. Each row is a bacterial taxon, with the proportional abundance of that taxon depicted by color corresponding to the annotated key (top right). Last row represents Jaccard index of each sample which is depicted by color corresponding to the annotated key (bottom right). The stability index remained similar across groups, suggesting that disease state does not significantly affect this β-diversity metric
