Methods: We triangulated two pre-specified streams. Individually, we analyzed 3,268 NHANES 1999-2004 participants aged 40 years and older with ankle-brachial index measurements (235 with PAD) linked to mortality through 2019, using survey-weighted logistic and Cox models, a Fine-Gray model, and attributable fractions.
