Fig 6.

Partial least-squares (PLS) plots of the structure of the association between the amount of gp340; PRP allelic types (e.g., Db and PRP2), phenotypes (e.g., Pp4), and amounts (PRPtot); and the adhesion of S. mutans Ingbritt to saliva from donors from a caries case-referent sample (n = 218) or from high- or low-adhesion saliva extremes selected thereof (n = 81) (bottom). The variable importance in the projection (VIP) is given for selected variables (right). pc[1], correlated variation; po[2], noncorrelated variation (noise).
