* : Stage 1 is adjusted for age, self-rated health, diagnosed illness, annual income, and home ownership. Stage 2 is adjusted for age, self-rated health, diagnosed illness, other social relationships, annual income, and home ownership.
† : To calculate the hazard ratios, “no” (coded=0) of each variable is used as a reference.
§ : To calculate the hazard ratios, multi-generation household is used as a reference.
