  1. A Chi-square goodness-of-fit test was performed to compare our samples’ birth month (in quarters) to the average Canadian births by months. The Canadian births are the averages of the percentages of Canadian live births per month between the years 2002 and 2008 [42]. Quarter 1: January–March; Quarter 2: April–June; Quarter 3: July–September; Quarter 4: October–December
