Comparison of 3 and 6-Month Postsurgery Sensation Status of ENSMSLS Patients With That of NSM Patients

Parameter	NSM (n = 30)	ENSMSLS (n = 30)	OR*	95% CI of OR	P
Pressure sensation decrease	28/30	12/30	21.00	4.20, 105.04	<.0001
(3 months)
Pressure sensation decrease		11/30	24.18	4.82, 121.61	<.0001
(6 months)
Temperature sensation decrease	30/30	25/30	13.16‡	0.69, 249.48‡	.02
(3 months)†
Temperature sensation decrease		23/30	19.47‡	1.06, 358.38‡	.005

Vibration sensation loss		0/30	31.24‡	1.73, 563.16‡	.0006
(6 month)§
Nipple transposition	16/30	12/30	1.71	0.62, 4.77	.30

Sensation status in the matched NSM group was conducted only once, on the day when they were called back for re-examination.

^*Odds ratio of patients in the NSM surgical group compared with patients in the ENSMSLS group.

^†Because all the patients in the NSM group had a drop in sensitivity to temperature, the OR cannot be calculated normally. The risk decrease for the ENSMSLS group vs the NSM group was 16.67% in 3 months and 23.33% in 6 months.

^‡All logit estimators with this marker use a correction of 0.5 in every cell of those tables that contain a zero.

^§For vibration sensation change; because no patients in the ENSMSLS group had lost their vibration sensation, the OR cannot be calculated normally. There was a 33.33% risk decrease for ENSMSLS group compare to NSM group at both the 3 and 6 month follow-ups.
