  1. Covariates with univariate p < =0.1 were analysed using multivariable regression. aTransformed for normality by square-root and Odd’s Ratio (OR) is expressed as the increase in odds of new atrial arrhythmia for 1 standard deviation increase in the normally transformed variable. bOR 1.9 (1.01–3.50), p = 0.046 in multivariable logistic regression with LVEF. *Univariable factors with significance p<0.1 were included in multivariate analysis
