Subject: how to summarize results from studies?
In-Reply-To: <A3E6755A-8D4A-4227-B277-91B4841A8269@me.com>
Thank you Marc!
I ended up using metafor library:
res_UK <- escalc(mi=data_UK$GAD.7_mean, sdi=data_UK$weight_pred, ni=data_UK$GAD.7_mean_N, measure = "MN?)
rma(yi, vi, data=res_UK, method="REML?)
