2.5. Statistical analysis
Statistical analyses were performed using GraphPad Prism software version 9.3.1 (GraphPad Software) to evaluate the differences in mRNA expression of three placental models exposed to pro-inflammatory cytokines or inflammation stimulants. The data obtained are presented as mean ± SD and median ± interquartile range of at least three independent experiments where appropriate. The statistical significance of differences between groups was analyzed with one-way analysis of variance (ANOVA) or nonparametric Wilcoxon signed rank test where appropriate.
