What the study showed, in plain terms

This publication examines incident coronary heart disease. Study population or evidence base: 16,057 women without cardiovascular disease at baseline. Intervention or exposure: Habitual dietary K1 and K2 intake estimated by food-frequency questionnaire.

Key findings

Higher dietary menaquinone intake was associated with lower coronary heart-disease incidence, particularly for longer-chain menaquinones.

What this study can and cannot tell us

Diet was not randomized. Residual confounding, dietary measurement error and differences between foods and supplements limit causal interpretation.
