Fig. 2From: Mentholation affects the cigarette microbiota by selecting for bacteria resistant to harsh environmental conditions and selecting against potential bacterial pathogensBox plots showing alpha diversity (Chao1 richness estimator and Shannon Index) variation across samples on non-rarefied data (a) and with data rarefied to the minimum sampling depth (b). Bars are colored by mentholation status: red bars—non-mentholated; green bars—user mentholated; blue bars—custom-mentholated; purple bars—commercially-mentholatedBack to article page
