Nomogram for predicting risk of malnutrition for stable COPD patients. Values for each variable are individually plotted and correspond to point values assigned from the point scale (top). These point values are then totaled and plotted on the total point scale (bottom), which is used to assign a corresponding value for prediction. 6MWD 6-min walk distance, WHR waist-to-hip ratio, AE acute exacerbations during the past year.
