Even the term "randomized" implies a control group, as one cannot randomize
in the absence of a control group!

Subject: Re: Research Study Design
Dear Rachel,
A randomized controlled trial is, by definition, controlled
(www.cebm.net/?o=1116). So, either the authors of the study have used the
term 'RCTs' incorrectly (unfortunately this does happen), or they have not
explained what the control group is clearly and you have overlooked it.
I hope this helps.
Best wishes,
Jeremy

Hello
I am just asking for your advice surrounding a research study design. I am
performing a systematic review on a number of articles which investigate the
effect of a neuromuscular training versus a traditional strength training
protocol in ACL injured individuals.
The studies state to be randomised control trials however as no control is
present is this correct or should they be termed randomised comparative
trials? Also what appraisal tool can be used with these studies?
Thank you in advance
Rachel
