Article Synopsis
  • Stepped-wedge cluster randomized trials are studies that change between two groups (control and intervention), which means they can use fewer groups, but there are no clear rules about the minimum number of groups needed.
  • The authors looked at 61 small trials done between 2016 and 2022 to find out how they're designed and analyzed, discovering that many used just two to six groups.
  • They found reasons for using fewer groups, like wanting to avoid mix-ups between them and having limited options, but many still did not explain the small number clearly.

Background/aims: The stepped-wedge cluster randomized trial (SW-CRT), in which clusters are randomized to a time at which they will transition to the intervention condition - rather than a trial arm - is a relatively new design. SW-CRTs have additional design and analytical considerations compared to conventional parallel arm trials. To inform future methodological development, including guidance for trialists and the selection of parameters for statistical simulation studies, we conducted a review of recently published SW-CRTs.

Article Synopsis
  • Children and families are increasingly participating as equal partners in child health research, but there's a lack of attention to authorship issues in this area.
  • A study analyzed 230 articles from 12 systematic reviews on patient engagement in child health, finding that only 7% listed patient partners as authors, while 18% acknowledged them by name in the acknowledgment sections.
  • The results indicate that patient partners are more often acknowledged than formally credited as authors, highlighting the need for better understanding and support for their roles in research.

Background: There are few data on patient and public involvement (PPI) in pragmatic trials. We aimed to describe the prevalence and nature of PPI within pragmatic trials, describe variation in prevalence of PPI by trial characteristics and compare prevalence of PPI reported by trial authors to that reported in trial publications.

Methods: We applied a search filter to identify pragmatic trials published from 2014 to 2019 in MEDLINE.

Objectives: In stepped-wedge cluster randomized trials (SW-CRTs), clusters are randomized not to treatment and control arms but to sequences dictating the times of crossing from control to intervention conditions. Randomization is an essential feature of this design but application of standard methods to promote and report on balance at baseline is not straightforward. We aimed to describe current methods of randomization and reporting of balance at baseline in SW-CRTs.
