But Magda Havas, of Trent Unviersity in Ontario, Canada, says that scientists are demanding impossibly high standards of studies.
New U.S. rules should ensure assessment of subjects' understanding, compensation for injury, and standards of study quality.
Method: This article addresses several aspects of research on cognitive enhancement in schizophrenia, emphasizing how the assessment of cognitive function in clinical trials requires certain standards of study design to lead to interpretable results.
We integrated eCODES into an equally secure Web-based data entry and management system (see Figure 2 and Additional file 2, "Security standards of study data system used to present eCODES").
Strengths include the comprehensive search in two main databases, as well as strict adherence to standards of study selection, classification, and reporting.

However, there remains no gold standard measure of study quality for observational research.
The gold standard of study design for treatment evaluation is widely acknowledged to be the randomized controlled trial (RCT).
Randomized trials are considered the gold standard of study designs, but have not been fully applied to understand the effects of bioactives and nutrients.
While randomized controlled trials (RCT) are currently considered a gold standard of study design, they are not always available and do not represent the only study format that can lead to best available evidence.
