The percentage of samples harboring individual pathofunctions in metagenomes (MTG%, n = 278 (XII); n = 311 (XIII)) and metatranscriptomes (MTX%, n = 78 (XII); n = 305 (XIII)) as well as correlations between abundance and expression levels (Spearman’s rho and p value) based on matched MTG/MTX samples (n = 78 (XII); n = 304 (XIII)) are shown. Ratio refers to the median RNA/DNA results of matched samples where only pairs that showed values > 0 at both levels were considered. nd: not determined. Seven metatranscriptomic samples and one metagenome from dataset XIII were omitted due to low sequencing depth (< 10⁵ reads). Significant differences (*p < 0.05) between abundance and expression based on generalized linear models are indicated
