Serum tau and survival. Survival curves for tau, modeled by Cox proportional hazards regression, adjusted for age are shown. Tau was used after log10 transformation. Tau was used as a continuous variable in these models, but predicted survival curves (with 95% confidence intervals) are shown for 3 different levels of tau, corresponding to the median level within the lowest, middle, and highest tertile of tau, respectively. Greater serum tau was significantly associated with shorter survival in all models.
