The correlation of cathepsin S, cystatin C, or cathepsin S/cystatin C with either FEV1% or LAA score in the AR and COPD groups (n = 125). Cathepsin S levels correlated modestly but significantly with FEV1/FVC (a) and inversely with the LAA score (d) (r = 0.261, p < 0.01; r = −0.228, p < 0.05, resp.); also cathepsin S/cystatin C ratios correlated modestly but significantly with FEV1/FVC (c) and inversely with the LAA score (f) (r = 0.242, p < 0.01; r = −0.223, p < 0.01, resp.). In contrast, cystatin C levels did not correlate with either FEV1/FVC (b) or LAA (e).
