*Values are from multivariable models with anthropometric and clinical values as predictor values and P‐wave indices as response variables. Values shown are for variables retained in the model, determined by their significant association with any of the P‐wave indices (P ≤ 0.10) in age‐ and sex‐adjusted analysis. Age and sex were forced into these models.

**Values in parenthesis are a standard deviation change for continuous variables.
