PRISMA is a good one.

Thanks, but PRISMA for reporting ( writing systematic review). My question is about evaluating literature systematic reviews. 

I mean if someone doing paper to evaluate the EXISTING SR, which tool shall he/she use?

Thank you Jakub. I agree with using AMSTAR

There is a updated (I think) tool called R-AMSTAR - very easy to use. 

Dear Heba,

AMSTAR is a good tool for your purpose ('content' quality of published SR). Nevertheless, we should try PRISMA when evaluate a SR, too.

Hi

I agree with Dorothy. R-AMSTAR is better then AMSTAR

Good luck
