How did you determine whether overlapping subjects were included in multiple studies?
If multiple studies drew upon the same large cohort (e.g., ADNI, Swedish BioFINDER), we assumed overlap and selected the paper with the largest number of subjects. When subjects in multiple papers with common authors were described as being drawn from the same medical clinics, the corresponding author(s) were contacted and asked whether there was any overlap of subjects among the studies; if the authors indicated that there was significant overlap, the paper with the largest number of subjects was selected for the meta-analyses.
