Background: Previous studies suggest that dietary vitamin C is inversely associated with gastric cancer (GC), but most of them did not consider intake of fruit and vegetables.

Methods: Fourteen case–control studies were included in the analysis (5362 cases, 11,497 controls...

We estimated summary odds ratios (ORs) and the correspon...
