Anatomical-electrical coupling of cardiac axes: Definitions and population variability for advancing personalised ECG interpretation

Fig 8

Regression coefficients illustrating the relative influence of BMI, age, and sex on cardiac anatomical and electrical axes.

The standardised coefficient, , indicates the change in the angle per standard deviation of the predictor. Absolute values of the coefficients represent the strength of impact each variable has on the angular metrics. Note that coefficient of sex is not standardised by standard deviation and is for Male compared to Female. All multicollinearity and goodness-of-fit results can be found in Tables A–E in S1 Appendix.
