High quality RCTs will randomize patients, and as important, conceal that randomization. Why? To limit selection bias. Selection bias is best described as a fundamental difference between the patients included in the treatment arms of a study due to the way in which patients were allocated to ...
FR feature in IRT.FR with a carefully chosen drug supply/re-supply strategy can result in quantifiable improvements in the patients' and site personnel experience, trial logistics and efficiency while preventing an undesirable refusal to randomize a patient and a consequential unblinding at the site....
88 The low certainty evidence is based on observational data because it is not logistically or ethically feasible to randomize individual children to those who have breastfed or not. We found one RCT addressing more versus less breastfeeding and the development of AD among healthy breastfed ...
This challenge is particularly evident in the surgical field, where comparative studies, often complex to design, face difficulties in inclusion, with patients and surgeons reluctant to randomize because of a strong prior belief in the superiority of one treatment over another [2]. Such a ...
the systems currently in place; predefined criteria allow the IxRS to randomize subjects in different strata and can be performed separately within each stratum. The capacity of these systems to handle randomization represents a significant benefit to the accuracy and safety of the trial in many ...

- The pilot has to be placed in the context of the main study. Can I randomize patients in a pilot study? - Yes. For a phase III pilot study, one of the goals could be to assess how a randomization procedure might work in the main study or whether the idea of randomization might ...
A randomized controlled trial to evaluate the effectiveness of a cognitive behavioural group approach to improve patient adherence to peritoneal dialysis f... Background Peritoneal dialysis (PD) requires patients to take an active role in their adherence to fluid restrictions. Although fluid non-...
Pragmatic trials are another real-world approach that randomizes patients to the treatment of interest or to standard of care and then follows them under real world conditions to evaluate effectiveness in broader populations than are typically included in RCTs. As an example, in 2021...
at warp speed because US COVID-19 cases surged in the fall. “These are case-driven trials,” Greg Glenn, MD, president of research and development at Maryland-based Novavax, whichbegan enrollingpatients in the US and Mexico in its phase 3 trial in late December, explained in an ...
