Boxplots of seven significantly changed species in PD vs. controls (FDR < 0.05). Significance levels were determined using multivariable semi-parametrical fractional regressions with the group variable (PD vs. control) as a predictor of interest, including age, gender, BMI, and technical variables (total read counts and sequencing run (batch)) as covariates.
