The ethnic differences in distal gastric cancer attributable to infection were estimated by comparison of the baseline age-standardized rate ratio (SRR; Māori men compared with European/other men) with an SRR calculated as though all distal gastric cancer cases occurred among the infection, and the population standard used for age standardization.
Quantitative bias analysis methods to adjust the data for confounding by smoking were also undertaken.
Details of these sensitivity analyses are provided in the electronic supplementary material, and the results were not substantially affected.
was greatest in the Pacific population at 71% and 82% of the relative difference in distal gastric cancer rates in the two cohorts born in 1924–1940 and in 1941–1955 respectively compared with the European/other population.
All serum samples drawn in 1982 were thawed for the first time and analysed in June 1993.
Circulating Ig G antibodies against a low molecular weight (LMW) fraction of antigens were measured in duplicate by using an in-house indirect enzyme linked immunosorbent assay (ELISA).28 The Ig G serology assay had previously been validated in 151 adult Danes with dyspeptic symptoms.
People with epigastric pain and increased levels of Ig M antibodies to infection rates are slightly higher in people with non-ulcer dyspepsia (NUD) than in asymptomatic people.6-10 Other groups have succeeded in linking specific gastrointestinal symptoms, such as postprandial bloating and belching, to the presence of infection poses other problems.
Acute infection occurs primarily in childhood and is rarely seen in adults. Consequently, it has been difficult to attain a consistent clinical image of this condition.
