^aAll models are survey-adjusted, and include controls for SES, marital history, functional health, and other predictors listed in Appendix Table A1.

^bNumber of network members is treated as the exposure variable.

^cNote that this model also includes an interaction b/w age and avg. frequency of interaction w/net members.

^dNumber of possible relationships among network members, given network size, is treated as the exposure variable.

^eSeemingly unrelated estimation test of whether including the life-course factors significantly alters the association b/w age and connectedness.
