Kaplan-Meier curves of the cross-classification of large, medium, and small social networks and low and high levels of social support from a spouse/partner, family, friends and neighbors. Women with small social networks and low levels of social support had a significantly elevated risk of all-cause mortality over follow-up (HR=1.61, 95%CI: 1.10–2.38), compared with women with large networks and high levels of support (reference) but no other groups exhibited an elevated risk compared with the reference group.
