‡
P for Interaction assessed the interaction between literacy and randomization and language and randomization for each outcome
Number of participants in each group:
- Participants with limited literacy assigned to redesigned advance directive, n= 41 and assigned to the standard, n= 41
- Participants with adequate literacy assigned to redesigned advance directive, n=62 and assigned to the standard, n=61
- Spanish-speaking participants assigned to redesigned advance directive, n=33 and assigned to the standard, n=27
- English-speaking participants assigned to redesigned advance directive, n=70 and assigned to the standard, n=75
