Nosebleeds and serum iron, categorised by dietary supplement use. (A) Epistaxis severity score (ESS): The ESS ranges from zero (no nosebleeds) to 10. As outlined in Figure 1, the non iron supplements comprised vitamins (N = 15), fish oil (N = 8), glucosamine, coenzyme Q10, alpha lipoic acid, echinacea, magnesium, and evening primrose. Median values indicated. 3 group comparison, p = 0.075 by Kruskal Wallis. (B) Serum iron in the 50 study participants. Note that the institutional normal range is 7–27 µmol/L. Median values indicated. Overall Kruskal Wallis p-value = 0.033. Data from all 50 study participants.
