Household response rates will be measured as the proportion of households that complete all
interviews and report food acquisitions for the seven-day period. (Additional tables will
present proportions of households with partial responses.)
Table B1 presents the power to detect differences in proportions between two treatment

foods from food bank. Items measure individual food items obtained from all food acquisition
events.
