The correlation between serum levels of A1AT, MMP-9 and MPO in PiZZ patients receiving Prolastin therapy.

<p>(<i>A</i>) Spearman correlation analysis shows a significant positive correlation between the serum levels of MMP-9 and MPO (r = 0.7284, p<0.0001, n = 56); A1AT and MMP-9 (<i>B</i>) as well as A1AT and MPO (<i>C</i>) (r = 0.34, p = 0.009, n = 56; and r = 0.32, p = 0.016, n = 56, respectively). Line represents linear regression of data (MMP-9 with MPO: slope 0.1471±0.0175, r2 = 0.567; A1AT with MMP-9: slope 245.9±62.5, r2 = 0.223; A1AT with MPO: slope 35.54±12.98, r2 = 0.122).
