Variables	Snail^low, 𝑛 (%)	Snail^high, 𝑛 (%)	P value
Stage
I/II	1 (5.3)	18 (94.7)	0.574
III/IV	4 (9.5)	38 (90.5)
Grade
1	0 (0)	5 (100)	0.591

3	2 (6.5)	29 (93.5)
LN metastasis
No	4 (9.3)	39 (90.7)	0.666
Yes	1 (5.9)	16 (94.1)
Responses
CR/PR	5 (10.2)	44 (89.8)	0.561
SD/PD	0 (0)	3 (100)
Platinum sensitivity*
Sensitive	4 (12.5)	28 (87.5)	0.594
Intermediate	1 (7.1)	13 (92.9)
Resistant	0 (0)	6 (100)

LN: lymph node; CR: complete response; PR: partial response; SD: stable disease; PD: progressive disease.
*Platinum sensitivity was defined according to the time interval from the date of last chemotherapy cycle to the first evidence of recurrence; sensitive when the interval was >12 months, intermediate when the interval was >6 months and <12 months, and resistant when the interval was <6 months.
