Comparison of NNMT expression among benign, primary, and metastatic cancer tissues.

	Benignendometrium	Benignomentum	PrimaryEC	Metastatic EC	P
NNMT score (overall)	14.9 ± 10.1	25.8 ± 26.8	64.8 ± 71.7	140.3 ± 117.6	<0.001*

*Benign endometrium vs. primary tumor, P = 0.001 (Mann–Whitney U test). Primary tumor vs. metastatic omental tumor, P < 0.001 (Wilcoxon signed rank test). Metastatic omental tumor vs. benign omental tissue, P <0.001 (Mann–Whitney U test).

NNMT: Nicotinamide N-methyltransferase, EC: endometrial cancer.
