Allcause
mortality versus BMI for each sex in the range 15–50 kg/m² (excluding the
first 5 years of followup). Relative
risks at ages 35–89 years, adjusted for age at risk, smoking, and study, were
multiplied by a common factor (ie, floated) to make the weighted average
match the PSC mortality rate at ages 35–79 years. Floated mortality rates
shown above each square and numbers of deaths below. Area of square is
inversely proportional to the variance of the log risk. Boundaries of BMI
groups are indicated by tick marks. 95% CIs for floated rates reflect
uncertainty in the log risk for each single rate. Dotted vertical line
indicates 25 kg/m² (boundary between upper and lower BMI ranges in this
report).
