Relation between surgical TNM stage and preoperative delays

Preoperative delay	TNM stage	No. of patients	No. of days			p value^*
Preoperative delay	TNM stage	No. of patients	Mean	SD	SE	p value^*
From first onset of symptoms or physician visit to surgery	I–II	186	201.1	292.1	21.4	0.57
	III–IV	64	227.1	369.3	46.2
	Total	250	207.7	313.1	19.8
From first contact with surgeon to surgery	I–II	187	104.9	99.9	7.3	0.75
	III–IV	65	100.3	97.6	12.1
	Total	252	103.7	99.1	6.2

SD = standard deviation; SE = standard error.
↵* Analysis of variance was used to compare differences between means. Significance was set at p < 0.05.
