The minimum score for each question was 0 (no symptoms) and the maximum score was 10 (feel the worst with symptoms) P⁰ = difference among 1w, 1 m and 3 ml; P¹ = difference between 1w and 1 m; P² = difference between 1 m and 3 m, P³ = difference between 1w and 3 m; P* means significantly difference.
