I mostly use Review Manager, which is a free tool that lets you create basic meta-analyses with good looking forest plot figures and risk of bias plots. Stata is another meta-analysis tool where you can make basic and more advanced statistical analyses, such as meta-regression, but the figures look like something from the 80s.
As well as 'Review Manager' mentioned by Martin Bjorn Stausholm, which I have used for Cochrane Review, I have also found 'Rayyan' and 'Covidence' very useful.
A nice review that compares features of the main leading systematic review softwares can be found here: Article Web-Based Software Tools for Systematic Literature Review in...
I would consider using Nested Knowledge (https://nested-knowledge.com/), as it allows you to complete every step of the systematic review process directly in the software (search, screening, data extraction, risk of bias, etc.). It also allows you to easily update your review at any time and can be used to complete living systematic reviews with modern-looking interactive visualizations. This is a relatively new system, but is in my opinion both the most user friendly and most comprehensive.
Dear Martin Bjørn Stausholm I know this is not helping you but I need your help. Revman sofware is no longer available from Cochrane's website and I need it for my my metaanalysis. Could you share the file with me via google drive or something? I'm desperate about this issue. Thank you in advance.
