The data is displayed as the back transformed mean difference of experimental group minus control group (confidence interval of difference). Values > 1 depict larger values for the experimental group compared to the unstimulated control cultures. The *indicates a significant difference of p < 0.05, the ƚ indicates significant difference of p < 0.01. The back transformed means (CI) are not equivalent to means of the original variable due to mathematical twisting [27].
