In an article by S.F. Duffy et al in the October 2005 issue of Hypertension (Duffy SF, Biegelsen, ES, Eberhardt, RT, Kahn DF, Kingwell, BA, Vita, JA. Low-renin hypertension with relative aldosterone excess is associated with impaired NO-mediated vasodilation. Hypertension. 2005;46:707–713) The lower panel of Figure 4 is incorrect. Whereas the legend and data symbols are correct in the upper panel, the symbols are reversed in the lower panel. As shown in the corrected figure below, the subjects in the highest quartile of aldosterone-to-renin ration tended to have the lowest response to sodium nitroprusside, however, this response did not differ from the responses of subjects in the other 3 quartiles (P=0.37). Overall as reported in the article, there was no significant relation between quartile of aldosterone-to-renin ratio and the vasodilator response to sodium notroprusside.
