Logistic models examining variables associated with positive lymph nodes.

OR1 (95% CI2) OR1 (95% CI2)
Mitotic Rate ≥1: 2.13 (1.92 – 2.37)
<1: 1.00 (reference)		 1.19 (1.17 – 1.21)
(per mitosis /mm2)
Ulceration 3.53 (3.13 – 3.97) 2.94 (2.59 – 3.33)
Breslow Depth 0.991 (0.989 – 0.992) 0.992 (0.990 – 0.993)
Age 0.994 (0.990 – 0.997) 0.993 (0.989 – 0.996)
Gender Female: 0.79 (0.71 – 0.88)
Male: 1.00 (reference)		 Female: 0.82 (0.73 – 0.91)
Male: 1.00 (reference)
Race Caucasian 1.00 (reference)
AA3: 1.75 (0.92 – 3.31)
Other: 0.67 (0.42 – 1.07)		 Caucasian 1.00 (reference)
AA3: 1.66 (0.87 – 3.19)
Other: 0.63 (0.40 – 1.02)

Both models adjusted for all variables listed. Mitotic rate treated as a dichotomous outcome in the first column, and continuous outcome in the second column.
