On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
Although randomisation ensures the elimination of selection bias the ‘standard’ two armed trial is not without its difficulties. Many participants have a treatment preference, which can introduce post-randomisation bias. Attrition is a problem in most trials with 20% or more attrition not being uncommon. Similarly trials can be slow and expensive.
A TWICs design can potentially address some of these problems. Essentially a TWIC is a RCT that is embedded within a larger cohort. Elements of the design can mean that attrition is lower, participant preferences are dealt with, costs are lowered due to the use of unequal allocation and existing cohorts. In this talk I will discuss the basic elements of the design and the experience of the York Trials Unit in its use.
