Angiogenin concentration in hypertension.

<p>Patients with hypertension were characterized by lower serum concentration of angiogenin than healthy individuals (Mann- Whitney U test; p = 0.01). The data are presented as medians (symbols inside the boxes), 25–75% percentiles (boundaries of the boxes) and minimum—maximum (error bars outside the boxes). Statistical significance (p<0.05) is marked with “*”.
