Figure 4(a). Stroke mortality (11 663 deaths) versus usual total cholesterol. Age-specific associations for total stroke.

Conventions as in figure 1(a).

NOTES: There was a weak positive association between total cholesterol and total stroke mortality at ages 40-59 years, but little association at older ages. When the MRFIT and PSC findings were combined (table 2, webfigure 7), there was a weak positive association with total stroke at ages 40-59 and 60-69 years, but not at older ages.
