Primary prevention of coronary heart disease in women through diet and lifestyle. Assessment of the transitivity assumption Transitivity is the fundamental assumption of indirect comparisons and network meta-analysis, and its violation threatens the validity of the findings obtained from a network of studies.
Does chocolate reduce blood pressure? Eur J Clin Nutr 58 Am Heart J 4: Greenland S Quantitative methods in the review of epidemiologic literature. Control Clin Trials 7 3: J Clin Epidemiol 53 2: This study showed for the first time an inverse association between chocolate consumption and subclinical atherosclerosis coronary artery calcium.
In this model, the relative risk for LA represents its substitution for the same percent of energy from carbohydrate. Search term Structured Abstract Objectives: Prospective studies based on children, adolescent or pregnant women will be excluded.
Pflugers Arch. Hamling J, Lee P, Weitkunat R, Ambuhl M Facilitating meta-analyses by deriving relative effect and precision estimates for alternative comparisons from a set of estimates presented by exposure level or disease category.
Acute effect of oral flavonoid-rich dark chocolate intake on coronary circulation, as compared with non-flavonoid white chocolate, by transthoracic Doppler echocardiography in healthy adults.
Arch Intern Med Available at http: Stata J 6 1: We also excluded studies conducted in patients with known CHD at baseline.
Cocoa and cardiovascular health. Our search terms combined the exposure LA with various CHD outcomes, and the full details on the search strategy are presented in the Supplemental Material. Am J Clin Nutr 99 1: Heart Attack and Angina Statistics. Public Health Nutr 14 12A: J Nutr.
In addition, we included the results of three other previously published studies. We performed a systematic review and meta-analysis of prospective cohort studies to summarize the evidence regarding the relation of dietary LA intake and CHD risk.
Procyanidin and catechin contents and antioxidant capacity of cocoa and chocolate products. Short-term administration of dark chocolate is followed by a significant increase in insulin sensitivity and a decrease in blood pressure in healthy persons.
For example, we will assess whether discrepancies in amount of intake or definition of exposure of the same foods across studies are likely to render some nodes in the network intransitive. After screening the titles and abstracts, full-text articles were evaluated which 6 original articles were identified as being appropriate for inclusion in this meta-analysis.
Therefore, in nutrition research, well-designed prospective cohort studies are the main source of evidence to address decade long exposures populations with hard clinical endpoints [ 5 ].
J Agric Food Chem. To the best of our knowledge, no systematic review and meta-analysis has compared simultaneously the effects of multiple dietary factors on all-cause mortality, cardiovascular disease, cancer disease and risk of type 2 diabetes.

Can we now eat chocolate without feeling guilty? CBS News. Our inference about the plausibility of transitivity will be based on the following criteria: The search strategy identified unique citations Figure 1. We captured study information such as cohort characteristics, risk model characteristics, model performance statistics, and quality review elements.
