Association between log PfGLURP seroprevalence and gSG6-P2 IgG: log odds ratio and standard error (SE), 95% confidence interval (95% CI), p-value, random-effect variances (ψ), conditional intraclass correlation coefficient (ICC) (ρ)* and model log likelihood (ℓ) from logistic mixed-effects modelling.^† This analysis is based upon n = 116 study-specific observations.

*ρ = , where ψ_k through ψ_nk are random-effect (RE) variance estimates pertaining to each of the respective variance components (see table notes ^{‡ and §}) from generalised linear multilevel model (mixed effects, logistic) for a specific ICC estimate.

^†Generalised linear multilevel modelling (mixed effects, logistic) estimating the association between log PfGLURP seroprevalence and anti-gSG6-P2 IgG seropositivity with random effects for study-specific heterogeneity in gSG6-P2 IgG seropositivity.

^‡ψ₁ represents variance of the random effect for study.

^§ρ₁ represents conditional ICC for salivary antibody observations from the same study.
