Significant level (P) computed between Group 1, 2, 3, 4, 5 only. Group 6 was not included due to small size (n=2) only, ^#Fisher’s exact test used, ^†Kruskal- Wallis H-test used. Multiple comparisons used for NRS, P<0.05 significant. At 18 h: Between Group 1 to Group 2, 3, 5 and Group 4 with Group 2, 3. At 24 h: Group 2 with Group 1, 3, 4 and Group 5 with Group 1, 4.
