Random effects
γ = 0.131, θ = 0.088, τ = 4.2%

P value = P value for Likelihood-ratio test of theta = θ at chi-square with 0 and 1 degrees of freedom, θ = theta (variance of random terms), τ = Kendaell’s tau, Coeff = Coefficient of factors, St.err = Standard error of coefficient, ϕ = Odds Ratio
Bold values indicate to make the identification of included covariates in the study simple for readers and to easily distinguish the significant covariates
