There are three critical components of a clinical trial: (1) the prospective nature of data collection, (2) the introduction of an intervention, and (3) the comparison of patients receiving the intervention to prospectively followed patients who do not receive the intervention.
Performing sample size calculations prior to a study and ensuring adequate patient recruitment, is a crucial component of preserving a trial's methodological rigour.
This approach gives us better control of the history of CS responses and allows more definitive conclusions about the components of trial-over-trial changes in neural responses.
Pharmacokinetic optimisation that ensures adequate time above minimum inhibitory concentration should therefore be an integral component of any trial that compares duration of antibiotic therapy [ 5].
The severity of this toxicity remains to be established and predicting and managing it will be an important component of any trial protocol.
The secrecy, redactions and delays in release of information mean that the public does not have contemporaneous access to the proceedings, a fundamental component of a public trial.
[ 1] Our finding that most people with Type 2 diabetes who are eligible and willing to attend yoga classes in our London setting are from non-white ethnic groups, lower socio-economic backgrounds, and close to or above retirement age suggests that a key component of a future trial should probably be 'marketing' the idea of yoga to a group who might not otherwise be drawn to this activity.
We attribute this component of trial-over-trial-depression to CS-linked plasticity that occurs during trial-over-trial behavioral learning, because it persists after we control for same-trial facilitation.
Key dietary components of the trial include a description and evaluation of food consumption patterns including glycemic index and glycemic load, novel assessments of gluten quantification, and objective and subjective measures of GFD adherence.
This paper was developed from the first phase of a project funded by the Medical Research Council (project reference G0701759) Developing the intervention & outcome components of a proposed randomised controlled trial of screening for open angle glaucoma.
