Multivariate Cox regression analysis of high expression levels of NUAK2 in relapse-free survival of acral melanoma patients

Variable*	Hazard ratio	95% confidence interval	P value
NUAK2	3.88	1.44–10.50	0.0075†
Sex	0.87	0.38–1.97	0.73
Age	1.31	0.55–3.11	0.55

*Coding of variables: High expression of NUAK2 was coded as 1 = negative; 2 = positive. Sex was coded as 1 = male; 2 = female. Age was coded as 1 = ≥60 y; 2 = >60 y.

^†P < 0.05.
