^a EPPM categories: LT/LE - Low threat/low efficacy, LT/HE - Low threat/high efficacy, HT/LE - High threat/low efficacy, HT/HE - High threat/high efficacy
^b Reference category for odds ratio and 95% confidence intervals [OR(95%CI)] is LT/LE
^c Tests null hypothesis of no difference between EPPM categories
^d NS - Not statistically significant at p = 0.05 level
