“Resting-state fMRI in Parkinson's disease patients with cognitive impairment: A meta-analysis”: Answer to Wang and colleagues

We would like to thank dr. Wang and his colleagues for their interest in our study. While the authors address important measures to assess the validity of a meta-analysis such as heterogeneity between studies, the pooling of Parkinson's disease (PD) patients with mild cognitive impairment (PD-MCI) and patients with dementia (PDD) and the ON or OFF state during scanning, it is important to recognize the need for sufficient power when performing subgroup analyses.
