Random-effects models for trachomatous trichiasis or corneal opacity in adults over 40 years in Nigeria.

OR: odds ratio; BCI: Bayesian credible interval; DIC: deviance information criterion (smaller DICs indicate better model fit); ϕ = rate of decay of spatial correlation; σ2 = variance of random effect
a Non-spatial random effect only;
b Including separate spatial random effect for northern areas of Nigeria (North-East and North-West zones)
