Fig. 3From: Facial tremor in patients with Parkinson’s disease: prevalence, determinants and impacts on disease progressionSMD in baseline covariates between patients with and without FT before and after IPTW. SMD of baseline confounding covariates that were included for estimating the propensity scores before and after weighting. All the values of SMD were < 10% after IPTW weighting, which indicated there was a between-group balance after weighting. UPDRS III: Unified Parkinson’s disease Rating Scale part III. H&Y stage: Hoehn and Yahr stage. BMI: Body Mass Index. FAB: Frontal Assessment Battery. MoCA: Montreal Cognitive Assessment. HDRS: Hamilton Depression Rating Scale. HARS: Hamilton Anxiety Rating Scale. NMSS: Non-Motor Symptoms Scale. LEDD: levodopa equivalent daily dosage. SMD: Standardized Mean Differences. FT: facial tremor. IPTW: inverse probability of treatment weightingBack to article page
