We used simulation modelling to derive simple quantitative rules of thumb that can be applied by trialists, reviewers, and editors to ensure that subgroup analyses are properly contextualised and used by readers to quickly evaluate the credibility of a specific subgroup finding.
On the other hand, around 20% will develop distant metastases and this figure can be reduced by adjuvant chemotherapy (Early Breast Trialists, 1998).
Large PMAs such as the Blood Pressure Lowering Treatment Trialists Collaboration recently published [ 47] demonstrate how this methodology can be used very effectively to assess treatment effects in specific subgroups.
Beyond this, trialists and ethicists could consider how far communication about trials can be configured around the needs and preferences of individual parents [ 68] as well as the social norms of the setting [ 25].
While no design achieves the perfect balance of sensitivity and efficiency, clinical trialists continue to work toward the goals of smaller and shorter trials so that more compounds can be studied concurrently.

When aiming to minimise CO2 emissions, trialists and funders should focus particular attention on the emissions generated by participants' travel and travel by the trial team, which can be reduced with simple changes.
The area under the curve (AUC) analysis can be a simple method of capturing clinically relevant information associated with chronic conditions [ 19, 20], but it has not gained traction among the AD clinical trialist community.
Empirical evidence has shown that trialists can attempt to achieve a positive trial using multiple strategies and this is a very real concern [ 28].
Instead it suggests how trialists can engage with the complex dynamics of the settings in which they hope that their interventions will be implemented.
