Fig 4. The effect of MR2 hydrolysate on cell viability of three cell lines after 24h of incubation.

The results are presented as box plots. Asterisks indicate the significance of difference. However one has to notice that due to the testing of differences between all variants, different star colors were used. The variants differ significantly only if the asterisk color is various. Black asterisk means that selected variant differs with all the others. In contrast, the same color indicates that difference is statistically irrelevant. Moreover, number of asterisks (*; ** or ***) refers to p < 0.05; p < 0.01 and p < 0.005, respectively.
