So I'm going to change the original summary I've posted on Minimal Important Differences (MID). The studies of Ward et al. 2014 and Swigris et...
I don't know. We're mostly doing the calculation to get the original value. The study the Cochrane review cites for the minimal important...
Thanks. I've added you to the list.
Some more info from here: https://c-path.org/wp-content/uploads/2017/05/2017_session5_scoringfinal.pdf EDIT: if we use the formula here, the 7.1...
You could be right. Swigris et al. 2010 said they recalculated the MID raw value for Kosinski et al. 2000 (reported as 7.7) to a norm-based value...
I've been searching but can't really find the full explanation. I suspect it's explained in this reference: Ware JE, Kosinski M, Bjorner JB,...
Yes, That's probably my mistake. The value of 3 for the SF-36, for example, was a normalised value. I'm trying to figure out how to recalculate...
Wouldn't that be visible as a smaller standard deviation (SD)? In the three anchoring studies the SD was 6.6, 5.2 and 5.8 so not particularly...
Thanks for pointing this out! Yes, it was a normalized score. I didn't realize this could make a big difference to points on the scale. The Ward...
9) Minimally important differences I’ve been reading up on the issue of minimally important differences (MID), the smallest difference that...
Don't think so. Mean baseline score and standard deviation for the exercise group: 1335.27 (280.99) Mean baseline score and standard deviation...
Didn't know that. Higgins is a big name. He's the main author of the Cochrane handbook, both the old and new version. He's also from Bristol.
So Wise & Brown (2005) say that "The minimal clinically important difference (MCID) for the 6MWT is conservatively estimated to be 54-80 meters."...
This is from the GRADE handbook: Link: https://gdt.gradepro.org/app/handbook/handbook.html#h.3183vuv3ey12

Thanks for your support, you're on the list now. Welcome to the forum. Hope you'll stick around.
8) Lack of blinding Larun et al. have downgraded the quality of evidence of pretty much all outcomes in their review due to a lack of blinding...
Thanks for giving your perspective @Lucibee As someone with no statistical background, I was surprised that baseline differences are ignored in...
Thanks :), You're brilliant @Andy It was really puzzling for me.
Yes, the link I posted was to the 2001 protocol (https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD003200/full). For some reason, I...
