25OHD, 25-hydroxyvitamin D; CI, confidence interval; OR, odds ratio; PD, Parkinson disease.

^⁎

ORs are provided for the supplemented group (reference category: non-supplemented group, OR = 1).

^†

Adjusted for age, sex, body mass index, PD, and number of other comorbidities.

^‡

Adjusted for age, sex, body mass index, PD, and ischemic heart disease (the only comorbidity associated with mortality in univariate analysis).
