Socio-economic status and oesophageal cancer: results from a population-based case–control study in a high-risk area

Abstract

The strong association of SES with OSCC after adjustment for known risk factors implies the presence of yet unidentified risk factors that are correlated with our SES measures; identification of these factors could be the target of future studies. Our results also emphasize the importance of using multiple SES measures in epidemiological studies.
