Stable state cFLC levels relate to renal function. Scatter plots (a, b) and bar charts (c, d) showing the relationship between cFLC (mg/L), eGFR (ml/min/1.73 m2) and chronic kidney disease (CKD) stage in the stable state in A1ATD and usual COPD patients respectively. P values are for 2 tailed univariate statistics. A1ATD (a) rs = −0.14, p = 0.003 (c) p = 0.006. Usual COPD (b) rs = −0.24, p = <0.001 (d) p = <0.001. A1ATD CKD stage 1 (n = 156), 2 (n = 279), 3 (n = 41), 4 (n = 2), 5 (n = 1). Usual COPD CKD stage 1 (n = 119), 2 (n = 130), 3 (n = 35), 4 (n = 4), 5 (n = 0)
