Association of hemoglobin concentration with cardiovascular risks and all‐cause mortality after 10‐year follow‐up among young women. A, Association between hemoglobin concentration and acute myocardial infarction after a 10‐year follow‐up among young women. B, Association between hemoglobin concentration and stroke after a 10‐year follow‐up among young women. C, Association between hemoglobin concentration and cerebrovascular disease after a 10‐year follow‐up among young women. D, Association between hemoglobin concentration and all‐cause mortality after a 10‐year follow‐up among young women. Hazard ratio analyzed by Cox proportional hazards regression analysis adjusted for age, socioeconomic status, physical activity, smoking, alcohol, body mass index, blood pressure, fasting plasma glucose, total cholesterol, and Charlson Comorbidity Index (95% confidence interval). HR indicates hazard ratio.
