finally, a worth-watch video about heterogeneity ! I only have a question about last part. my forest plot showed a data that chi square = 32.42, tau square =0.61, df=1 (P=0.0007) and I square=66% . how can I conclude that? the number of sample in my stdy are below 20.
Thank you and it was helpful. I'd like to ask about if I sequare 75% or more, what is the best way to reduce the heterogeneity? Also, is my comparing will be true?
