They also - and this is the kicker - rated the random sequence generation of the trial as "at low risk of bias" despite there being no random sequence generation (the study didn't even use the word "random" or any similar term)pic.twitter.com/b8B1fs5j6Q
The study is here check for yourself: http://www.annfammed.org/content/11/5/452.long#ref-6 …
Thing is, that's maybe not a big error. A single matched cohort included in a review that supposedly only looked at RCTs But that was just the first review I picked out. I wonder how common this is?
Most people don't go through eligibility criteria and comb through studies to check systematic reviews - it's incredibly time-consuming and tedious. I know I don't Maybe we should

So did we. And found major problems:

And currently have a systematic assessment of 24 matched-pair MA’s submitted to @JClinEpi doing exactly this.
Just realised, I should pre-print this.
Would this be ok @JClinEpi ?
David Nunan added,
Definitely. I'd love to read it. Not even thinking about the in-depth stuff from the salt case, just boring basic checking against inclusion criteria and PRISMA to see if there are clear errors
Like...not even checking all the complex stuff such as correct ROB assessments. This is just me wondering why I rarely go through and check the basic aspects of the trial to see if they did what they said they did as I would do for a normal trial

That's actually brilliant, although your comment being open-access but the editorial being behind a paywall is very funny
