2.5. Statistical analysis
Data from the UPLC-Q-TOF-MS were analyzed using the MassLynx V4.1 software (Milford, MA, USA). Data results are represented as mean ± standard deviation. Statistical analysis was performed using IBM SPSS Statistics 25 software (New York, USA). Groups were significant by the Duncan test in analysis of variance (ANOVA), which were considered statistically different at P < 0.05. The Pearson’s correlation test was used to determine the relationship between breast milk triacylglycerol composition and maternal dietary intake. Boxplots were plotted using GraphPad prism 9.0 (California, USA). Correlation heat maps were plotted using TBtools software (Guangdong, China). Principal component analysis (PCA) plots were plotted using SIMCA 14.1 software (Demo Umetrics, Umea, Sweden).
