Endotoxin concentrations presented in EU m-3. Bar represents geometric mean, annotations present groups of statistical significance (p =< 0.05). E.g. Within group 'a' there is no statistical difference, while groups 'a' and 'b' are significantly different from each other.X-axis crosses at lower limit of detection, 0.152 EU m-3.
