  • Title: Lack of association of poultry and eggs intake with risk of non-Hodgkin lymphoma: a meta-analysis of observational studies.
    Author: Dong Y, Wu G.
    Journal: Eur J Cancer Care (Engl); 2017 Sep; 26(5):. PubMed ID: 27405484.
    Abstract:
    We carried out a meta-analysis to explore the association between poultry and eggs consumption and non-Hodgkin lymphoma (NHL) risk according to the published observational studies. A search of databases was performed in MEDLINE and EMBASE from their inception to March 2015. We derived meta-analytic estimates using random-effects models, and assessed between-study heterogeneity using the Cochran's Q and I2 statistics. We identified a total of nine case-control and three prospective cohort studies, including 11,271 subjects with NHL. The summary relative risks for high vs. low analyses were 1.04 (95% confidence intervals [CIs]: 0.86-1.27; pheterogeneity <.001, I2  = 84.0%) for poultry consumption and 1.15 (95% CIs: 0.87-1.51; pheterogeneity <.001, I2  = 85.3%) for egg consumption. Meta-regression analysis showed that study locations, study quality, type of Food Frequency Questionnaire and confounders adjusted for total energy intake contributed to the high heterogeneity among the studies on poultry consumption, whereas no significant factors were responsible for the high heterogeneity among the studies on eggs consumption. Limited data suggested a null association between consumption of poultry and eggs and NHL subtypes. Findings from our meta-analysis indicate that consumption of poultry and eggs may be not related to NHL risk.
