Bubble chart showing the relationship between PLS X’s component, representing the enteric pathogen community, and the severity of diarrhea (MNLS per 24 h) in 850 children aged below five years in Kunming, southwest China. In the PLS X’s component, virus richness, RVA (here shown as rotavirus), and NoV GII (shown as norovirus) were the most important variables of enteric pathogen PLS X’s component. On the other hand, diarrhea severity (response variable) was represented by the MNLS per 24 h. The initial set of variables representing the X’s component can be seen in Table 3. Bubble size indicates virus richness that ranged from 0 (virus free) to three virus types (children co-infected with RVA, Ad, and NoV). Bubble color, however, indicates a specific co-infection. The horizontal grey dotted line shows the 90th percentile
