Filtering the deluge of new research to facilitate evidence synthesis has proven to be unmanageable using current paradigms of search and retrieval. Crowdsourcing, a way of harnessing the collective effort of a "crowd" of people, has the potential to support evidence synthesis by addressing this information overload created by the exponential growth in primary research outputs. Cochrane Crowd, Cochrane's citizen science platform, offers a range of tasks aimed at identifying studies related to health care. Accompanying each task are brief, interactive training modules, and agreement algorithms that help ensure accurate collective decision-making.The aims of the study were to evaluate the performance of Cochrane Crowd in terms of its accuracy, capacity, and autonomy and to examine contributor engagement across three tasks aimed at identifying randomized trials. ⋯ Cochrane Crowd is sufficiently accurate and scalable to keep pace with the current rate of publication (and registration) of new primary studies. It has also proved to be a popular, efficient, and accurate way for a large number of people to play an important voluntary role in health evidence production. Cochrane Crowd is now an established part of Cochrane's effort to manage the deluge of primary research being produced.

This text builds on a conversation with Dr. Gordon Guyatt who provided guidance to trainees on interdisciplinary collaboration and work-life balance as part of a graduate-level biostatistics course in September 2020. The participants in the conversation comprised a group of clinicians, methodologists and biostatisticians, ranging from junior trainees to world-renowned established researchers. ⋯ As an invited guest, Dr. Guyatt shares his experiences after decades of leadership and successful international collaborations. He emphasizes the importance finding the right mentor, forming productive collaborations, developing self-awareness, and strategies for achieving a work-life balance.

Comparing observed and expected distributions of categorical outcome variables in randomized controlled trials (RCTs) has been previously used to assess publication integrity. We applied this technique to withdrawals from RCTs. ⋯ Comparing the observed and expected distribution of trial withdrawals may be a useful technique when considering publication integrity of a body of RCTs.

To present a structured approach for assessing stakeholder perceptions and implementing the approach in guideline development. ⋯ The FACE criteria propose a series of knowledge translation questions to guide the assessment of implementation for evidence-based guidelines. It is desirable for guideline developers to use a conceptual approach, such as FACE, to tailor implementation and inform end of guideline dissemination and knowledge translation activities.

The Trials within Cohorts design aims to reduce recruitment difficulties and disappointment bias in pragmatic trials. On cohort enrollment, broad informed consent for randomization is asked, after which cohort participants can be randomized to interventions or serve as controls without further notification. We evaluated patients' recollection, understanding, and acceptance of broad consent in a clinical oncology setting. ⋯ Patients adequately remember giving broad consent for randomization shortly after cohort enrollment and after being offered an intervention, but recollection is lower in those never selected for interventions. Patients are acceptant of serving as control without further notifications.
