1
AMPM, Automated Multiple-Pass Method; ASA24, Automated Self-Administered 24-hour Recall.
2
Two participants in the ASA24 group and one in the AMPM group did not consume breakfast at the study center and were excluded from this analysis.
3
One participant in the ASA24 group did not consume dinner at the study center and was excluded from this analysis.
4
P values are for recall mode (ASA24 and AMPM), adjusted for race-ethnicity, and were calculated by using linear regression for matches and exclusions and Poisson regression for intrusions and number of items reported.
