Use of pharmacological rescue (Y/N) 8/18 (44.4 %) 11/21 (52.4) 0.75 0.079
Emesis (Y/N) 2/18 (11.1 %) 2/21 (9.5 %) 0.87 0.026
Continued use of intervention (Y/N) 5/18 (28 %) 14/21 (66 %) 0.048 0.33
Reduction in BARF scale magnitude 3.8 (95 % CI ±3.7) 3.2 (95 % CI ±2.4) 0.52 0.01
  1. Reduction in BARF magnitude is expressed as mean and 95 % CI. The means were compared using T-Test with calculation of effect size. Otherwise data are expressed as percentage of subjects meeting the outcome (binary Y/N) and means were compared using Chi-Square test with calculation of effect size
