Fig 2 Bivariate scatter plot of pre-labour predictive EPTs and outcome response measures with significant Pearson's correlations. (a) Heat tolerance (x-axis) with labour worst VPS (y-axis). (b) Pain with i.v. cannulation (x-axis) with time to epidural (y-axis). VPS, numerical verbal pain score (0–10; 0, no pain; 100, worst pain imaginable); i.v., i.v. peripheral (18 G, forearm) cannulation (pain rating VPS during insertion).

Fig 3 Scatter plots of pain during labour AUC numerical verbal pain score (AUC VPS) and the fitted values from the multiple-regression modelling. The solid line represents the line of y=x, and the vertical distance from the line for each point represents the deviation of the observed value from the predicted mean value from the regression model.
