Table 3 Multivariate logistic regression analysis Inuit women with depleted iron stores as the dependent variable 1-2

From: Higher n3-fatty acid status is associated with lower risk of iron depletion among food insecure Canadian Inuit women

  1. 1 Women with hs-CRP > 10 mg/L and women with elevated iron stores were excluded from the model (n = 1062 in final model).
  2. 2 For highly prevalent outcomes, the odds ratios will tend to exaggerate the true relative risk.
  3. 3All variables presented were evaluated together in one model. The within-dwelling variance component was 0.1.
