Table 2 Results of the multivariate logistic regression model

From: Spatial epidemiology of porcine reproductive and respiratory syndrome in Thailand

Variables Mean coefficient Mean SE* Mean odds ratio (OR)
Adjusted odds ratio 95% confidence interval
Constant −2.611 0.428   
No. of human population 0.479 0.253 1.669** 1.024 -2.779
No. of farms having breeding sows 1.750 × 10-2 1.823 × 10-2 1.016 1.004-1.029
Autoregressive term 2.438 0.521   
  1. *SE stands for standard error.
  2. **The odds of a sub-district being PRRS positive was increased by a factor of 1.669 (95% CI 1.024 to 2.779) for every 10,000 unit increases in the number of human population in a sub-district.
  3. Results of the multivariate logistic regression model (Model I) with 100 bootstraps applied for analyzing PRRS presence/absence at the sub-district level in Thailand.
