U-shaped: both low and high values carry risk. Not measured in our NHANES panel; the curve is synthesised from the published association.
Hazard ratio relative to the curve's reference value, as synthesised from the published association.
Published hazard ratio0.87per SD (95% CI 0.83–0.90) · Systematic review and meta-analysis of 20 population-based cohort studies (17 examining all-cause mortality)
