  1. Percent change in owner-reported pruritus scores. By day 60, diet B owners reported a significant reduction of 46.4% in itching. Data are reported as median (range).* P value to compare groups within each day. P value to compare days within each group. Within each column, days with different superscript letters differ from each other (p < 0.05)
