I'm doing a meta-analysis looking at the effectiveness of psychotherapy at post intervention and follow-up. One study has only pre, 6 month and 12 month follow up data. Is it appropriate to use 6 month data for post and 12 month for follow up if I state that I'm doing so?
Hi Charlotte, Send me a message, I can help you further if you need. But what I would do is exclude the pre data study as there is only one and wouldn't provide any significant heterogeneity. So do 6 month as pre and 12 as post no problem. It's weird that there is only one study that is looking at pre data, nevertheless, using 6 month data is fine and popular among the literature.
Hi Mara,
Sorry, I'm a little confused by your answer. I just wanted to clarify. The studies I have provide pre-intervention, post-intervention and follow-up data. So I'm looking at the post-intervention data to begin and then follow-up data in a seperate analysis. However, one study only provides pre-intervention data, 6 month follow-up and 12 month follow-up data. Can I fit this into both the analyses that I want to do?
Thanks,
Charlotte
Ohh sorry for confusion. Post vs. follow-up is fine. Since one only includes pre, I would not enter the pre data.
