  1. aThe variables included to the multivariable model were those with P ≤ 0.20 in the univariable analysis; bOdds ratio adjusted for the variables in the table, Horro breed of sheep was dropped due to collinearity with origin. The bold P-values are significant.
  2. Factors associated with T. gondii seropositivity in study zones with their category, adjusted odds ratio (aOR) and corresponding 95% confidence interval (95% CI) in the final multivariable logistic regression model.
