* = significant test; OR = odds ratios; CI = odds ratios confidence interval at 95%; null model= −2ln(L₀), where L₀ is the likelihood of obtaining the observations if the independent variables do not affect the outcome, the full model: −2ln(L₀), where L₀ is the likelihood of obtaining the observations with all independent variables incorporated in the model; C = chi-square test.
