U-shaped: both low and high values carry risk. In NHANES 1999–2018 with linked mortality to 2019, each standard deviation is associated with a hazard ratio of 1.03. U-shaped: slope not comparable
NHANES, our fit with 95% CIPublished curve
Hazard ratios relative to each curve's own reference value, so the two curves need not cross 1 at the same point. The dotted vertical line marks the NHANES median.
