Normal-weight women are displayed as ○ and overweight/obese women as •. Difference between EI and TEE is shown on the y-axis and TEE on the x-axis. The mean difference is displayed as – – – – – and the limits of agreement (mean ± 1·96 sd) are displayed as ······. The regression lines are displayed for normal-weight women ( – - – - – ) and overweight/obese women (———)
