  1. aThe p-value is calculated by a chi-square test. Odds ratios (OR), with confidence intervals of 95% (95% CI), were calculated
  2. bHas not been added to the calculation. *The P-value is significant
  3. cWhere zeros cause problems with computation of the odds ratio, 1 was added to all four cells
