Three years following the antibiotic colistin ban as livestock feed supplement and growth promotant, the prevalence of colistin antimicrobial resistance (AMR) among E. coff isolates from poultry and pigs were compared. The hypothetical data are: Species Year Prevalence (%)95% Confidence interval Poultry 2019 25 17-33 16 2020 120 12-28 16 2021 12 9-15 Pigs 2019 35 32-38 2020 125 21-30 2021 12 8-16 1. The conclusion about the E. coli AMR level in poultry from 2019 to 2021 is: Othere is no significant difference between the years. Othe only significant difference was between 2019 and 2021. Othere is significant difference between every year. Othe only significant difference was between 2020 and 2021. 2. The conclusion about the E. co// AMR level in pigs from 2019 to 2021 is: Othere is no significant difference between the years. Othe only significant difference was between 2019 and 2021. there is significant difference between every year. Othe only significant difference was between 2020 and 2021. 3. The conclusion about the E. coli AMR level in pigs and poultry is: Osignificantly different between pigs and poultry. Onot significantly different between pigs and poultry. Osignificantly different between pigs and poultry in 2019 only. Onot significantly different between pigs and poultry in 2019 and 2020. 4. The overall conclusion about the intervention implemented is: Onot effective. Oeffective Oeffective only in pigs but not in poultry. Oeffective only in poultry but not in pigs
