Differences in alpha diversity between RA status and probing depth. Alpha diversity was estimated using three different metrics: observed OTUs, Faithā€™s phylogenetic distance, and Shannon diversity. Boxplots show the median value and interquartile range (IQR) for each metric. Whiskers extend up to 1.5 times the IQR, and outliers that fall outside of that range are shown as dark points. Statistical significance of differences between groups is shown in TableĀ 2. OTUs operational taxonomic units
