HelIo everyone, Currently I am working on systematic review and meta-analysis of a surgical technique ( Posterior Scleral Reinforcement in high myopia and complications of high myopia ) to observe its effect. As there is no comparator in my study. So my question is,which type of study model I should apply and which software is most reliable for Meta-analysis?
Regards.
State your research question. Use PICO format. Based on your comment, I do not expect a "C" component. What is the rationale for not having a comparator?
What do you mean by "study model"? Fixed-effect model? Random-effects model?
I doubt that you are truly concerned about the reliability of a software. Reliability of an instrument assesses the reproducibility of the instrument, an issue I would not think a software program would have a problem with. Also remember that an instrument can have perfect reliability and be wrong 100% of the time. Validity (aka accuracy) would be more likely to be a problem. Still, I doubt that it would be an issue for any of the major meta-analysis packages. The "best" meta-analysis software is largely a matter of opinion. You pretty much get what you pay for, noting that several packages are free. The following URL shows six head-to-head comparisons of various meta-analysis packages to Comprehensive Meta-Analysis. It may be useful to you. The URL is at the CMA website so beware. (https://www.meta-analysis.com/pages/comparisons.php)
I think the best one is open meta analyst, but U need pre and post data. You can see this paper: doi: 10.5604/01.3001.0010.7532
