Figure 2. PCA illustrating the contribution of bacteria and antigen-presenting cells to OA progression according to the Lpps treatment. The dataset comprises bacterial counts in the digest tract and Peyer’s patches, body weight and bone marrow antigen-presenting cells (red circles) from 10 untreated and 10 Lpps treated rats. Blue circles correspond to the qualitative variables (i.e., OA progression and Lpps/water intake).
