Fasting glucose × blood pressure: risk of death across both

Glucose and blood pressure add up rather than interact: 30 mmHg more systolic pressure raises risk of death about 20% at any glucose level, and glucose above 7 mmol/L adds its own rise.

Risk of death relative to the reference, by contour band.
Cox model with restricted cubic splines and a Glucose × Systolic BP interaction (likelihood-ratio p = 0.32), adjusted for age and sex. NHANES 1999–2018 with linked mortality to 2019; 46,469 adults, 6,688 deaths (fitted surface). The path joins the average adult in each decade of age, and each oval holds the middle half of people that age (NHANES, unweighted). Different people at each age, so this is how the population differs by age, not one person's path. Population associations from US adults, not a personal risk estimate.

How to read the map

How to read it

Colour shows risk of death from any cause relative to the reference point. It comes from a Cox model fitted on 46,469 adults with 6,688 deaths (fitted surface). Each contour band is one step on the scale beside the map. Hatched areas hold too few people to estimate.

The read-out gives a 95% confidence interval at the marker: the range the data are consistent with. It reflects sampling uncertainty only, not model or confounding uncertainty. Show uncertainty fades the map, or swaps it for a map of interval width.

Try an intervention draws the average change one study measured in a marker as an arrow from the marker. The study's 95% interval shows as a faint bar or box at the arrowhead. It shows where that change would land on this map, not what the intervention would do for a person.

Up to three arrows can be chained, although effects from separate trials may not add. The interaction test asks whether the two markers combine differently from the sum of their separate effects (likelihood-ratio p = 0.32).
