^*Reference category: > 24 years.

^†Age as continuous variable had: bivariate (Coefficient = −0.039, Wald χ² = 34.67, and P < 0.001) and multivariate (Coefficient = −0.035, Wald χ² = 29.59, and P < 0.001).

^‡Omnibus test was not significant (the model did not outperform the intercept-only model).

^§Reference category: above secondary.

ITNs = insecticide-treated nets; NA = not applicable.
