Meta-analysis effect size problem

Hello everyone

I am a newbie here in doing meta-analysis

In my study i have around 9 studies but weight of one study is like >95%,

So in this case what are my options? should i exclude that study?

ps. its a medical research with little data available.

thank you
Thank you for the reply, yes i did all the quality control and it was well conducted. So would you recommend doing the analysis with and without taht particular study and including both results in my paper?


Less is more. Stay pure. Stay poor.
There is a sensitivity analysis for MAs, where you perform leave-one(study)-out. So you report the results after leaving each study out and running model on the rest.
