One result is a snapshot. Time makes a trajectory.
Calculate illustrative LDL concentration × duration across explicit intervals. This is arithmetic for organizing a clinician conversation, not a personal risk score or treatment recommendation.

Bundled example ready: age 20 to 35.
Clinical boundary: mg-years here is illustrative arithmetic, not a validated individual risk measure. Do not use it to diagnose disease or choose medication.

Why: 145 × 15 years = 2,175 mg-years in the unchanged illustration.
What it cannot say: this difference does not determine personal cardiovascular risk or treatment.
