Groups shown are those on atenolol therapy (treated-HT) and those who were untreated (untreated-HT).

CBF indicates calf blood flow; CVR, calf vascular resistance; and MSNA, muscle sympathetic nerve activity. Data are mean±SEM. P refers to unpaired t tests, and Fisher χ2 test in the case of gender.
