Statistical analysis
For descriptive analysis median values, mean values and standard
deviations were computed. T-tests were applied between the logarithmic
adsorption values (basis 10) of the extracts and the two control groups,
respectively, with a Bonferroni-correction due to multiple testing. For
graphical presentation of the results scatter plots were used. All
computations were done with STATA (Version 17.0, College Station, TX,
USA).
