↵* Compared groups using χ2 test (or the Fisher exact test when counts were < 5). We excluded the missing data category from the test when zeros were found in both Métis and non-Métis groups. For all comparisons, p values were less than 0.01 except for pregnancy outcome (p = 0.326) and neonatal death (p = 0.878).
