Systematically missing confounders in individual participant data meta-analysis of observational cohort studies.

One difficulty in performing meta-analyses of observational cohort studies is that the availability of confounders may vary between cohorts, so that some cohorts provide fully adjusted analyses while others only provide partially adjusted analyses. Commonly, analyses of the association between an exposure and disease either are restricted to cohorts with full confounder information, or use all cohorts but do not fully adjust for confounding. We propose using a bivariate random-effects meta-analysis model to use information from all available cohorts while still adjusting for all the potential confounders.

Global secondary prevention strategies to limit event recurrence after myocardial infarction: results of the GOSPEL study, a multicenter, randomized controlled trial from the Italian Cardiac Rehabilitation Network.

Background: Secondary prevention is not adequately implemented after myocardial infarction (MI). We assessed the effect on quality of care and prognosis of a long-term, relatively intensive rehabilitation strategy after MI.

Methods: We conducted a multicenter, randomized controlled trial in patients following standard post-MI cardiac rehabilitation, comparing a long-term, reinforced, multifactorial educational and behavioral intervention with usual care.

Incidence of new-onset diabetes and impaired fasting glucose in patients with recent myocardial infarction and the effect of clinical and lifestyle risk factors.

Background: Individuals with diabetes are at higher risk of myocardial infarction than non-diabetics. However, much less is known about the incidence of, and risk factors for, development of diabetes and impaired fasting glucose in patients who have had a myocardial infarction. We set out to estimate this incidence and investigate whether lifestyle factors such as dietary habits might alter this risk.
