Table 3. Redistribution of patients and gastric cancer resections after centralization.

Variables	GC resections performed in low volume institutions (<25 GC resections per year) to be redistributed	GC resections performed in high volume institutions (≥25 GC resections per year)
North	1,508 (52.7)	1,354 (47.3)
Central Italy	700 (49.2)	722 (50.8)
South and Sardinia	752 (66.3)	382 (33.7)
Total	2,960 (54.6)	2,458 (45.4)

Values are presented as number (%).

South and Sardinia vs. North: OR, 1.76; 95% CI, 1.531–2.040; P<0.001. South and Sardinia vs. Central Italy: OR, 2.03; 95% CI, 1.728–2.385; P<0.001.

GC = gastric cancer; OR = odds ratio; CI = confidence interval.
