MMP-2 and sTNF-R1 Variability in Patients with Essential Hypertension: 1-Year Follow-Up Study

<table>Bland-Altman plots for changes in MMP-2 and sTNF-R1 serum levels in hypertensive patients. Bland-Altman plot showing agreement between the logarithm of MMP-2 levels percentage change against the average of the logarithm of MMP-2 in basal stage + stage I, in the hypertensive patients (a). Bland-Altman plot showing agreement between the logarithm of sTNF-R1 levels percentage change against the average of the logarithm of sTNF-R1 in basal stage + stage I, in the hypertensive patients (b). The solid line represents the mean of the percentage change. The dashed lines define the limits of agreement (standard deviation of percentage of change <svg height="8.7875004" id="M21" style="vertical-align:-0.3135pt" version="1.1" viewbox="0 0 10.125 8.7875004" width="10.125" xmlns="http://www.w3.org/2000/svg">
