Table 1: Summary of the studies reported in humans and responses in terms of urinary volume (UV) and urinary sodium (UNa) excretion. Notes: i. Study refers to the design (P, parallel; CO, cross-over), whether the study was randomised (R?), whether a placebo control group (PL?) was included (simply yes [Y] or no [N]) and the population size (n). ii. Duration is shown in hours (h), days (d) and weeks (wk). iii. Dosage is shown when it was reported. iv. Other abbreviations: U, unclear; ‘↑’ and ‘↓’ represent significant increases and decreases, respectively; ‘→’, represents no change; and, ‘NM’, indicates when a parameter was not measured.
