Hello This message is not actually from Professor Ian Robinson, but from Liz Ackroyd, Research Administrator in Social Sciences and Law at Brunel University. Sadly, Ian has been in hospital for several weeks, following a stroke. He is making slow progress, but we do not expect him to be back at Brunel for quite some time. If you want to get any personal messages to him, please contact me for details: [log in to unmask] Would it be possible for you to remove him from this email circulation list?

All good wishes, Olive >>> "Maria Shepherd" <[log in to unmask]> 06/29/05 7:21 pm >>> Greetings- I am doing a project for my physical therapy schooling, and I wanted to ask for your input/assistance. I have two articles, both of which are systematic reviews. However, they each only examine one RCT, and the remaining articles reviewed (6 in one article and 10 in the other) are empirical/observational studies which don't have control groups. All of the findings were positive and concluded the same thing. I'm having trouble assigning a level of evidence to these two systematic reviews because they do only have one RCT. Would you mind providing me with some input as to what level of evidence you might think they would be and why? I appreciate your assistance. Thank you. Maria Shepherd, PT
