Past and Future Dependencies in Meta-Analysis: Flexible Statistics for Reducing Health Research Waste -- Judith ter Schure

This session will be a 10-minute practice talk with feedback. April 20th Judith gives a 10-minute talk at the NRIN Research Conference in the parallel session '2.1 Biases and solutions'<https://www.nrin.nl/agenda/nrin-research-conference-2018/>. Because the talk is so short, a practice round might help to get the focus right. Although the abstract involves all research topics related to meta-analysis, the talk will mainly discuss a newly defined phenomenon: 'Accumulation Bias'. Accumulation Bias is the bias in meta-analysis that occurs because clinical trials are, and ought to be, a dependent sequence; whether additional trials are performed and how many depends on previous trial results. See title and abstract below.
