Δ represents the % change in PCs per 10% decrease in LTL. Linear regression analyses were performed with log base of 2 transformations of LTL and PCs, with PCs as outcomes. ∆ was calculated as (2β − 1) × 0.10.

†

P values were derived from linear regression models.

‡

Model 1: Adjusted for age, gender, race (white vs non-white), BMI, smoking and previous MI.

§

Model 2: Adjusted for model 1 + absolute monocyte count. P values remained significant when monocyte count was replaced with total leukocyte, lymphocyte, or granulocyte count.

Abbreviations: LTL: Leukocyte telomere length. PCs: Progenitor Cells.
