From: Metagenomic analysis reveals differences in the co-occurrence and abundance of viral species in SARS-CoV-2 patients with different severity of disease

Fig. 2

Distance-based analysis of human virus communities among SARS-CoV-2 positive samples according to severity groups. The Analysis of Principal Coordinates (cap linear combination) is based on Bray Curtis-derived distance metric calculated on the abundance of human viruses in samples classified by the type of patient. Axes show the two Constrained Analysis of Principal Coordinates (CAP linear combinations) which are coerced by the type of patient. These account for 2.2% of total variation. Each sample is represented with a circle and distances show how similar they are from one another. Ellipses show within-group variation with a 0.75 confidence limit based on the standard deviation. Red circles represent ambulatory samples, blue represent hospitalized patients and fuchsia represents samples from deceased patients
