  1. Note: There were a total of twelve 24-hour urine collections labeled in the table as M1-M12, respectively. Mean osmolality values were compared directly with respective mean Pre-Treatment reference value which were averages of all M1-M3 values within the condition and subject group being evaluated. These Pre-Treatment reference values were as follows: 462 (all Control subjects), 490 (low PA), 436 (high PA), 525 (low SRWC), 405 (high SRWC), 468 (low PRAL), and 456 mOsm/kg (high PRAL). There were no significant differences detected for any of the evaluations.
