[R-meta] Multiple use of the same control

Dear list members,

I have a similar problem as Lasse Bang ( Follow-up - Dependencies in 
data: multiple studies with overlapping sample sizes).

I want to do a meta-analysis of studies with  time series, often with 
time series of several treatments and one control time series. To 
include all the treatments in the analysis, I therefore need to use the 
same control time series several times. How can I correct for that?

I am using  rma.mv with time as one of the modulators and StudyID (the 
publication ID) and SampleID (time series within the same study) as 
random effects, and a continuous-time autoregressive structure.

Thanks in advance for any advice.

Best wishes,
Arne Janssen
