Multiple comparisons in contrast analysis. Post hoc analysis of selected oxidative stress markers in NHDF cells exposed to different concentrations of lactones 1–3 (SC—starting concentration, MTC—minimal toxic concentration). Statistical significance was set at p < 0.05. Statistically significant values are bolded.

p_{SC vs. MTC} for lactone 1—SC values compared with MTC; p_{SC vs. MTC} for Lactone 2—SC values compared with MTC; p_{SC vs. MTC} for Lactone 3—SC values compared with MTC. Column SC shows comparisons between SC values for all three lactones. Column MTC shows comparisons between MTC values of all three lactones.
