24-h urine sodium excretion prior to the intervention in the groups. Sodium excretion was different across groups (Panel a, p = 0.0003). As shown in panel b, HIV positive hypertensive (HIV + HTN) excreted higher sodium in urine compared with HIV positive normotensive (HIV + NT) and HIV negative normotensive (HIV-NT) groups (p = 0.001) but not with the HIV negative hypertensive group (p = 0.89). Median and interquartile range for the groups in mmol/day: HIV + HTN 142 (124, 164), HIV + NT 102 (83, 115), HIV-HTN 127 (108, 147), HIV-NT 102 (81, 120). The overall mean (SD) sodium excretion in the population was 119 ± 35 mmol/day (2737 ± 805 mg/day of sodium or ≈ 6.8 ± 2 g salt/day). The minimum and maximum sodium secreted was 759–7, 920 mg per day (≈2 – 19 g salt). ***p < 0.001, **p < 0.01. Kruskal-Wallis (panel a) followed by Dunn’s multiple comparisons test (panel b)
