This is interesting, and raises the thought that perhaps we should be looking at connections between the things we do know. For example, we know PWP have higher levels of uric acid in their blood AND a (recently discovered) substantially different mix of gut bacteria than nonPWP. How could these conditions be related? What might the combination of these two factors mean? Has anyone studied the gut biome of PWP whose uric acid measured in the high range, and if so, what were the findings? I think we could learn a lot more meaningful things about PD if we started looking at the relationships between the things we do know, now.
