Fig 4. Prevalence of antimicrobial resistance to tetracycline and chloramphenicol exhibit decreasing linear trends from 2002–2016.

There are significantly higher odds for resistance to tetracycline for the 2002–2009 period when compared to the 2010–2016 period (OR: 1.87, 95% CI: 1.017–3.4). No significant difference in odds for resistance to phenicols for the 2002–2009 period when compared to the 2010–2016 period (OR: 1.6, 95% CI: 0.87–3.1).
