When interpreting the results of a clinical trial on a graph, what does a larger error bar signify?
A smaller deviation from a mean value and therefore smaller differences in the results of the trial
A larger deviation from a mean value and therefore larger differences in the results of the trial
That the clinical trial had errors and the results from it are not valid
What is a placebo-controlled clinical trial?
A trial where all the participants are split into groups at random
A trial where neither the participants or researchers are aware of which group has been given the drug being tested
A trial where a ‘dummy’ treatment that has no therapeutic value has been given to one group of participants
Why do double-blind clinical trials help reduce biased results?
Neither participants or researchers know who has been given the real drug
Participants in the trial are randomly assigned to groups rather than being picked by the researchers
Some of the participants have been given a fake drug and their results can be eliminated
Why is the diversity in the groups of participants in a clinical trial important?
To ensure the trial is representative of the wider population
To eliminates any potential prejudice on the part of the researchers conducting the trial
To give neglected members of the public a chance to be included in trials
