4. Figure E1
Kaplan-Meier curves for heart disease mortality across the longitudinal categories of insomnia. Insomnia was defined by International Classification of Sleep Disorders (ICSD) criteria and participants categorized into 3 groups: never insomnia (green), intermittent insomnia (blue), or persistent insomnia (red). While persistent insomnia was independently associated with increased risk for death due to cardiac disease, intermittent and never insomnia were not associated with cardiopulmonary mortality.

Kaplan-Meier curves for cardiopulmonary mortality across the longitudinal categories of insomnia. Insomnia was defined by International Classification of Sleep Disorders (ICSD) criteria and participants categorized into 3 groups: never insomnia (green), intermittent insomnia (blue), or persistent insomnia (red). While persistent insomnia was independently associated with increased risk for death due to cardiopulmonary disease, intermittent and never insomnia were not associated with cardiopulmonary mortality.

Kaplan-Meier curves for cancer mortality across the longitudinal categories of insomnia. Insomnia was defined by International Classification of Sleep Disorders (ICSD) criteria and participants categorized into 3 groups: never insomnia (green), intermittent insomnia (blue), or persistent insomnia (red). Neither persistent nor intermittent insomnia were independently associated with increased risk for death due to cancer.
