Forest plots of studies comparing Parkinson’s disease (PD) patients to controls. (a) Forest plots of studies comparing PD patients with general population showed a decreased risk of suicide in PD patients. (b) After excluding Myslobodsky’s study, forest plots of studies comparing PD patients with general population showed a significantly increased risk of suicide in PD patients. (c) Forest plots of studies comparing PD patients with non–central nervous system disease controls (healthy, psoriasis, or glaucoma) showed an increased risk of suicide in PD patients.
