Relative abundance at the family, genus, and OTU levels. RA BAL samples showed a significant decrease in Actynomyces (and related OTUs), Burkholderia (and related OTUs), and Treponema (and Prevotella-related OTU), compared to healthy controls. A similar trend for Burkholderia and the family Spirochaetaceae was observed for sarcoid BAL. The relative abundance (and presence) of the genus Porphyromonas in healthy BAL was also higher than in RA and sarcoid samples. *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001; ns non-significant
