Comparisons of bacterial counts between control subjects and PD patients.

aDetection rate represents the percentage of fecal samples that contained specific bacterial groups/genera/species above the detection threshold.bMean and SD are indicatedcStatistical difference is examined with Mann-Whitney U test.dq value is calculated using the Benjamini and Hochberg method.eStatistical difference is analyzed with Fisher’s exact test.fGram-negative bacteria. The sum of Gram-negative bacteria in PD (9.5 ± 0.6 log10 cells/g) was lower than that in controls (9.9 ± 0.6 log10 cells/g) (p U test).*p or q value is less than 0.05.n.s., not significant.Comparisons of bacterial counts between control subjects and PD patients.
