Table 1 also shows the translational assessment of PPARG and PPAR-γ in the experimental (animal models) and clinical (human) periodontitis studies. With the exception of the PPARG mRNA levels found by Chen et al. using RT-qPCR [33], all of the other data were statistically different between the periodontitis and control groups, as reported by the original articles. Here, PPARG is linked to periodontitis.
