About this episode
Researchers are heavily reliant on statistical techniques that are based on large sample sizes. Therefore, attempts to gain useful information from small samples can often lead to biased, or incorrect conclusions. Dr Rens van de Schoot at Utrecht University has shown that the limitations associated with small samples sizes can be overcome by using an alternative method – Bayesian estimation – as an all-encompassing approach to quantitative research. However, this approach comes at a price: expert knowledge must be integrated into the statistical model.

Professor Lobelia Samavati | Paving the Way for Antibody-based Diagnostics for Tuberculosis and Sarcoidosis
Tuberculosis – or TB – is a global health threat, with 10 million new cases annually. Diagnosing TB can be a challenge, as there is a lack of rapid, point-of-care diagnostic tests. It can also be difficult to distinguish between TB and other inflammatory diseases, such as Sarcoidosis. One option may be to identify antibodies in patient samples that can reveal the presence of TB. However, current antibody tests for TB lack accuracy. Professor Lobelia Samavati and colleagues at the Wanye State University School of Medicine in Michigan are tackling this challenge to cast light on the immune signature of these diseases. Their aim is to develop new diagnostic techniques for TB and Sarcoidosis.

Professor Ann Nevile | What Evidence Do Policymakers Need to Make Robust Decisions?
Policy decisions are influenced by many factors, from the ideology of the policymaker and their advisors to political expediency. Most would also agree that key political decisions should be evidence-based. However, this is easier said than done. Understanding what evidence policymakers need, and how they should evaluate this, is key for more robust decision-making.
