- Definitions of abbreviations: sRAGE = soluble receptor for advanced glycation end products (pg/mL); IQr = interquartile range. For the other abbreviations see table 1. The cutpoints of FEV1 % predicted are based on GOLD stage (see ref. [1]). The cutpoints for pack-years of smoking and DLCO % predicted are the median value in the whole sample.
