Separate ANOVA results are shown for each haemodynamic variable during six selected physical states or state-changes. ✓ = Statistical difference between pregnancy stage; X = No statistical difference between pregnancy stage, *p < 0.0005. Pairwise differences identified from post-hoc analysis are discussed in the text
