Table 1 Subject subgroup relationship to 1-year clinical diagnosis (standard of truth) and ioflupane [ 123 I] imaging results ( n = 92)

From: Association between Hoehn and Yahr, Mini-Mental State Examination, age, and clinical syndrome predominance and diagnostic effectiveness of ioflupane I 123 injection (DaTSCANTM) in subjects with clinically uncertain parkinsonian syndromes

Subjects with CUPS   Subgroup: H&Y stage Subgroup: MMSE score Subgroup: age of subjects at baseline Subgroup: clinical syndrome predominance at baselinea

  1. Data presented as numbers. B, balanced; BRP, bradykinesia, rigidity, postural instability; CUPS, clinically uncertain parkinsonian syndrome; H&Y, Hoehn and Yahr; MMSE, Mini-Mental State Examination; PS, parkinsonian syndrome; TD, tremor dominant. aTD, tremor score > BRP; BRP dominant, BRP > tremor score; B, maximal score of BRP = tremor score. Scores for these motor signs were 1 for none, 2 for possible, and 3 for definite.
