Systematic Reviews

Science-based Fitness and Nutrition has been blown but 100s of retracted articles. Sports Science and weight loss research misconduct and fraud are prevalent in top institutions and journals. Where can the public, trainers and nutritionists turn to?

Elder abuse, a critical human rights concern and public health issue, has been extensively studied in recent years. Various reviews have consolidated primary research to assess its prevalence. This vlog presents an umbrella review highlighting the significantly high estimated global prevalence rate of elder abuse in both community and care settings. Despite challenges like evidence quality and variability, it is undeniable that elder abuse is pervasive with a broad impact. The emphasis should now turn towards implementing interventions and policies to combat this type of abuse.

The integrity of research, especially in clinical trials, is crucial for the development of medications and treatments. Behind each breakthrough lie the contributions of countless patients who selflessly participate in these trials. Despite the current emphasis on COVID-19, there have been instances of research articles being retracted. While some retractions stem from unintentional errors or technical flaws rather than deliberate deceit, maintaining honesty throughout the research process is paramount. It is essential to recognize that the value of clinical trials heavily depends on the integrity of the data they generate. Surprisingly, many medical training programs do not adequately address the importance of clinical trial integrity. Moreover, numerous countries face challenges due to insufficient medical infrastructure and expertise in conducting trials. To enhance the credibility of clinical trials, transparency must be upheld at every research phase, starting from pre-registratio...

In health and medical sciences, with developments in computing, there is a rapid growth in data both in form of “Big” registries and published papers. Both offer opportunities to perform statistically powerful analyses, but each has its inherent challenges. Large datasets, in theory, offer consistent data, an assumption that ought to be tested concerning data quality in each project. Published studies that assess the same outcome but in different scenarios introduce the problem of variability in the results obtained by different researchers. A systematic review scientifically collates and investigates the literature to objectively summarize the evidence related to the research topic, using meta-analysis to statistically synthesize the results of individual studies where appropriate. These reviews can be used to underpin guidelines and recommendations. Evidence synthesis is also the essential ingredient for evidence-based medicine . Big Data, Meta-analysis and Systematic Reviews: The Ju...

This webinar by Professor Khalid Khan gives an overview of how to prepare tables and figures as part of data synthesis in a review. It also shows how to undertake meta-analysis. It is the seventh in an 8-part series of webinars given in the Slovenia doctoral training programme. Professor Khalid Khan is an author of the award-winning book titled "Systematic reviews to promote evidence-based medicine". Professor Khalid Khan is one of the 2% of the most influential researchers internationally.
