Cover Story: The metabolomic severity score (metSS) was developed with training data from the SPIROMICS study (n = 648) and validated in the COPDGene study (n = 1120). We attempted to design a score that predicts FEV1 with a group of metabolites, compared to single-metabolite models that have been published previously. From a set of 762 matched metabolites, the adaptive LASSO procedure selected 132 metabolites and estimated the weight for each metabolite to build a score. When combined with clinical covariates, the metSS added to the percent of FEV1 variability explained by 7% compared to clinical covariates alone. Selected metabolites in the metSS included metabolites previously shown to be associated with airflow obstruction and the progression of percent emphysema. Eventually, scores such as these may help to elucidate the pathobiology of COPD. View this paper
