A randomised controlled trial (RCT) is an experiment in which candidates are randomly assigned to one of two groups: the experimental group receives the intervention being tested while the other receives an alternative, or no intervention at all. The two groups are then compared to see if there...
Objective : To compare the survival and clinical outcomes of critically ill patients treated with the use of a pulmonary artery catheter (PAC) to those treated without the use of a PAC. Design : Prospective, randomised, controlled, clinical trial from October 1997 to February 1999. Setting : ...
Trial data will be coded at the entry stage using predefined structures. Back-ups will be made of the trial database on a monthly basis. Checks of data entry and eligibility are carried out at baseline for all participants prior to randomisation. Data will also be validated with source data...
The trial coordinator and trial statistician are not informed of group allocation. Within four weeks after randomisation, women in the group treatment arm attend six 1 1/2 hour sessions of group CBT, once a week for six weeks. Women from both arms attend post-treatment assessments in the two...
Based on the achievements of randomised controlled trials (RCTs) in medicine, and the need for effective government interventions in support of business, some have advocated for the use of RCTs in the evaluation of business support programmes (BSPs). Not
Registry-based randomised controlled trials (rRCTs) have been described as pragmatic studies utilising patient data embedded in large-scale registries to facilitate key clinical trial procedures including recruitment, randomisation and the collection of
(who generated allocation sequence / enrolled participants / assigned participants to interventions) at 51%, and item 24 (access to full trial protocol) at 31%. Reporting was also suboptimal around sample size calculation, randomisation methods, reporting harms / unintended effects and trial ...
It provides an opportunity to explore how the clinical trial road map fares in these settings. Whilst setting up BATH-OUT-2, we encountered challenges with securing funding for the trial, lack of non-NHS intervention costs, using research and support costs as intended, gaining approvals, ...

this purpose. As this work attests, ample research has been conducted in the field randomly assigning individuals or households to different treatments. When such randomisation is possible, factorial designs are an adequate tool to test main versus interaction effects42. Testing these main versus ...
