Does unblinding due to side effects lead to bias in placebo-controlled trials? And are active placebos a possible solution? (Spoiler alert: we are not sure.)

Last chance to participate - this will close on Sunday pm UK time. These results will be used to formulate guidance on demonstrating promise of an intervention when applying for funding for an RCT, pilot, or feasibility trial.

Funders expect evidence of 'promise' (the intervention is likely to work) when considering whether to fund an RCT, pilot, or feasibility study. But there is no shared understanding of how we should do this. We have been funded by
