^{a}Table values are n (column %) except for age which is represented as median (range). Statistical significance was taken to be p≤ 0.05 ^{b }N = 21 for age and female characteristics, n = 18 for tobacco/alcohol/diabetes due to missing data. Column percentages will not sum to 100%. ^{c }N = 60 for age and female characteristics, n = 47 for tobacco/alcohol/diabetes due to missing data. Column percentages will not sum to 100%. ^{d }pvalue calculated via Wilcoxon RankSum (age), Chi square (female), or Fishers exact tests (Tobacco, Alcohol, Diabetes)
