HR hazard ratio, CI confidence interval.
†Except for height, all exposure variables were treated as time-varying (i.e., modelled as recent exposure).
*HRs adjusted for age, sex, cohort, race, education, smoking, alcohol.
**Additionally adjusted for height.
^Includes data from California Teachers Study, Cancer Prevention Study II, Nurses’ Health Studies, Health Professionals Follow-up Study.
N represents the number of MM cases in each category.
