Fig. 2

Percentage of ASVs classified at each taxonomic level. The left panel shows results for the GTDB database and the right panel shows results for the Silva database. For each database, full-length and V4-V5 16S rRNA gene sequencing were compared (orange and blue, respectively). Boxplots were used to illustrate centrality metrics of the percentage of ASVs classified, including crosses representing the outliers and were calculated with 13 observations, per independent group. Note that the “Kingdom” taxonomic level was maintained to keep consistency with the terminology used by the reference databases used
