On certain trials, pulses of light could be delivered to the brain at specific points in the theta cycle.
These findings are in agreement with the results of certain trials (Flaherty et al, 2008; Hirashima et al, 2011).
While certain trials warrant some form of data monitoring, many do not need a formal committee, 326 such as trials with a short duration or known minimal risks.
8 Our findings regarding the nine drugs/indications discussed indicated that the variability in trials included across agencies seemed to be related to what were considered relevant comparators, manufacturer submission of different sets of trials to different agencies, and particular agency selectivity for inclusion or exclusion of certain trials.
This could result in the needless over-representation of particularly vulnerable cohorts of women in certain trials, such as sex workers (See ARVAC bulletin at http://www.arvac.org.uk/docs/info_bull100c.html), whose research findings, in addition, may not be generalisable to other women.
164 In certain trials, especially surgical trials, blinding of participants and surgeons is often difficult or impossible, but blinding of data collectors and outcome adjudicators is often achievable.
Cue-evoked cholinergic release events, termed "transients", were found to be associated with the detection of cues in certain trials.
Visual features necessary to predict a certain trial outcome consisted of the 1) position (spatial rule), and 2) color (non-spatial rule) of one of the circles.
Our relative inexperience in dealing with large quantities of information and our lack of familiarity with certain trial documents may limit our ability to assess risk of bias in clinical study reports.
The main limitation of our study is our relative inexperience in dealing with large quantities of information and our lack of familiarity with certain trial documents such as randomisation lists.
