  1. Note: There were a total of twelve 24-hour urine collections labeled in the table as M1-M12, respectively.
  2. Mean pH value differed significantly (P < 0.05) from respective mean Pre-Treatment reference value which was an average of all M1-M3 values within the condition and subject group being evaluated. These Pre-Treatment reference values were as follows: 6.23 (all Experimental subjects), 6.35 (low PA), 6.12 (high PA), 6.33 (low SRWC), 5.96 (high SRWC), 6.47 (low PRAL), and 6.02 (high PRAL).
