PARTICIPANT: What was driving the aldosterone and plasma renin activity responses? What was the relationship between those hormones and plasma volume, plasma osmolality, plasma sodium concentrations?
DR. FRANCESCONI: Well, the circulating sodium concentrations were actually not too different between groups, as Dr. Armstrong indicated. In addition to circulating sodium levels, circulating potassium levels, circulating protein levels, and osmolality were also not really significantly different.
