Figure 1. Temperature in diffusion-weighted imaging (DWI) abnormal (“ischemic”) brain is more strongly associated with body temperature later after stroke.

A 1°C higher body temperature is associated with a 0.5°C (95% confidence interval [CI] −0.6 to 1.6) higher temperature in DWI-abnormal brain at 16 hours (red line and dots), and a 1.2°C (95% CI 0.2 to 2.3) higher temperature in DWI-abnormal brain at 5 days (black line and dots).
