  • Data are shown as median (IQR) or numbers (percentages) and compared using the Mann-Whitney test or Fisher’s exact test as appropriate. Moderate alcohol excess is defined as per table 1. No alcohol excess is defined as consumption below these limits including no consumption at all. Bold values indicate p<0.05.
