^*First Nations Food, Nutrition and Environment Study. Data are unweighted.

^†P-values correspond to a multivariate logistic regression analysis of food security status and predictor variables. R² = 17 %. The analyses excluded participants with missing values for all predictor variables accounted for in the model. The variables excluded in the backward-stepwise selection method due to a lack of statistical significance and power include climate, contaminants and food basket costs.
