highly significantp = 0.001
Correlation was weak in early Braak stages I–II ( ρ = 0.064; FDR- p = 0.628), whereas stronger and highly significant correlation was found in later Braak stages: III–IV ( ρ = − 0.424; FDR- p = 0.001), V–VI ( ρ = − 0.440; FDR- p = 0.0004), and all stages combined ( ρ = − 0.430; FDR- p = 0.001).
