a

growth inhibitory samples are defined as those giving > 3 sd variation from overall average (across all plates, all samples at the same concentration).

b

inactive samples are defined as those giving < 3 sd variation from overall average.

c

True = % of individual assay reads correctly scored as “inhibitory” (i.e., the average of all repeats for that sample indicated significant inhibition) or “inactive.”

d

False = % of individual assay reads incorrectly scored as “inhibitory” (i.e., the average of all repeats for that sample was not inhibitory) or “inactive.”
