Odds ratios (OR) and 95% confidence intervals (CI) of the genetically predicted lifestyle factors with COVID-19 severe illness across Mendelian randomisation methods. OR and 95% CI were expressed as per standard deviation increase in genetically predicted levels in body mass index (BMI), lifetime smoking measure, accelerometer-measured physical activity and alcohol consumption (log-transformed standard drinks per week). The plots were right-truncated to better present the confidence intervals
