2.4. Statistical analysis
All data are shown as means ± SD (n = 3). The data were checked for normal distribution and homogeneity of variances. The data expressed as percentages (referring to fatty acids) were transformed with the arcsine transformation. The experimental design for the trial was factorial with 2 factors (2 × 2). Hence, the effects of the two factors and their interactions were analysed by two-way ANOVA (Statistica Version 10.0; StatSoft Inc., Tulsa, OK). The analysis of the simple main effects was done for both factors. Differences were regarded as significant when p < 0.05
