^*All reported P values are two-sided, with P < .05 considered as statistically significant.

^†For the multivariable analysis, characteristics were excluded if they were not related to the outcome (P ≥ .10), choosing against CPR.

^‡Health status was one of the following: excellent, very good, good, fair, or poor.

^§Health literacy was assessed with REALM. Three participants had missing data.
