for every behavior we have, three birth cohorts are walked forward to the modal age at which the behavior peaks, and the value at that hit-year is shown side by side. pre-lead 1900 to 1923. leaded 1971 to 1976. post-phaseout 1995 to 2000.
a fit means the leaded bar stands clearly above both neighbors for an outcome predicted to rise with lead, or clearly below for one predicted to fall. sequestered series stay in the dropdown with an amber badge and a stated reason. ecological association at the cohort's modal age, not individual causation.
For every behavior we have, three birth cohorts are walked forward to the modal age at which the behavior peaks, and the value at that hit-year is shown side by side. The pre-lead cohort was born 1900-1923, before commercial leaded gasoline (childhood lead from paint alone, low ambient). The leaded cohort was born 1971-1976, the peak childhood-lead generation (~16 ug/dL). The post-phaseout cohort was born 1995-2000, raised under <1 ug/dL. A fit means the leaded bar stands clearly above both neighbors for an outcome predicted to rise with lead, or clearly below for an outcome predicted to fall. Sequestered series are kept in the dropdown with an amber badge and a stated reason; the leaded bar is not expected to be elevated for those.
