Of late, clinical trial data, meta-analyses and observational studies have caused concern that the use of calcium supplements might increase the risk of myocardial infarction and stroke. A new meta-analysis suggests that there is no problem with calcium supplements, but as the analysis includes controversial data omitt…

Forest plots are frequently used in meta-analysis to present the results graphically. Without specific knowledge of statistics, a visual assessment of heterogeneity appears to be valid and reproducible. Possible causes of heterogeneity can be explored in modified forest plots. Forest plots in meta-analyses appear to be…

One of the most problematic issues in contemporary meta-analysis is the estimation and interpretation of moderating effects. Monte Carlo analyses are developed in this article that compare bivariate correlations, ordinary least squares and weighted least squares (WLS) multiple regression, and hierarchical subgroup (HS)…

I review some areas of medical statistics that have gained prominence over the last 5-10 years: meta-analysis, evidence-based medicine, and cluster randomized trials. I then consider several issues relating to data analysis and interpretation, many relating to the use and misuse of hypothesis testing, drawing on recent…

As in many areas of health care, treatments for cancer may differ only moderately in their effects on major end points, such as death. But, such differences are worth knowing about, particularly in common diseases in which they could represent a substantial benefit to public health. Large-scale randomized evidence allo…

Systematic reviews of randomized controlled trials often provide the most reliable information on which to base treatment policy. However, to be reliable, such reviews need to contain a high proportion of all the relevant randomized evidence. This relates both to the need to find all trials and the need to analyse data…

The main contributions of meta-analysis methodology to antiplatelet therapy in the field of cardiovascular prevention are presented with regard to the different sectors of the health system: help with therapeutic information, help in the planning of clinical trials for the pharmaceutical industry and help in decision-m…

Deteriorating efficiency in detecting critical events is a pervasive phenomenon. It has been asserted that the personality dimension of extraversion-introversion (E-I) could serve as a selection device: Introverts would be superior in sustained attention. A meta-analysis revealed better performance of introverts, but t…
