The above table shows a negative correlation between UPSIT scores and part III scores in the non-anosmia group (r_rm = −0.479, p = 0.006), related to Figure 3. Anosmia: baseline UPSIT < 19; Non-anosmia: baseline UPSIT ≥ 19. ADL, activities of daily living of PDQ-39; COG, cognitions of PDQ-39; LEDD, levodopa equivalent daily dose; MoCA, Montreal cognitive assessment; Part III, part III of movement disorder society-sponsored revision of the Unified Parkinson’s Disease Rating Scale; PDQ-39, Chinese-translated version of 39-item Parkinson’s Disease Questionnaire; Rmcorr, repeated measures correlation; r_rm, coefficient or repeat measurement correlation; UPSIT, traditional Chinese version of the University of Pennsylvania Smell Identification Test.
