Drug testing, too, would be simplified, as trial designers were able to select those more and less susceptible to the effect as the needs of the trial dictated.
Second, prior trials dictated both the rate and composition of fluids administered.
Given the baseline risks of thromboembolic events in this population, the sample size needed to detect even a 50% relative increase in risk (from 2.0%to3.0.0%) would be at least an order of magnitude larger than the trial protocol dictates.
The HIV-1 serodiscordant couples study design for this clinical trial was dictated by the need to directly assess whether HSV-2 suppressinn in an HIV-1 infected partner reduced the risk of HIV-1 transmission to their sexual partner.
Nevertheless, some types of trials or trial situations dictate the need for additional information in the trial report.
Finally, different trial designs dictate the most appropriate analysis plan and any additional relevant information that should be included in the protocol.
In many instances, ACRIN uses the traditional paired design of diagnostic trials which dictates that each subject receive imaging examinations by all the technologies under study.
The location of the target was selected randomly, and the reinforcement contingencies enforced on the trial were dictated by the visual cue that had appeared at that location earlier in the trial.
The patient selection is also an important criterion in future clinical trials to dictate the validity and efficacy of the tissue engineering regenerative strategies for safe translation in the daily clinical practice.
No publications describing NHS patients' current clinical pathways were identified, because trial protocol often dictates clinical practice.
