ALB and Parkinson disease: In nonadjusted model, higher albumin levels were related with the lower possibilities of all-cause death, but this significant relationship was not shown by the model II which adjusted by age, sex, PD disease duration, mHY stage, use of NSAIDs, CRP, MMSE (Table 3, Supplemental Digital Content, http://links.lww.com/MD/H152), but all OR values were <1, so insignificant association between baseline albumin level and all-cause death in model II might due to the small sample size of the study.
