From: Isolation and characterization of multiple drug resistance bacterial pathogens from waste water in hospital and non-hospital environments, Northwest Ethiopia

  1. R0 = Susceptible to all antibiotics tested; R1 = Resistance to 1 antibiotic; R2 = Resistance to 2 antibiotics; R3 = Resistance to 3 antibiotics; R4 = Resistance to 4 antibiotics; R5 and above = Resistance to 5 or more antibiotics. *P = value (>2 antibiotics) = (COR 3.74 1.49-9.53, 95% CI, P = 0.001).
  2. **P = value (≥R5 antibiotics) = (COR 9.43, 2.80-35.03; 95% CI, P = 0.00001).
