Contrasts of all conditions based on the flossing/discounting models in Experiment 1. Multiple comparisons were corrected using the Holm–Bonferroni method. Self-reported flossing frequency; Da: At least once a day. We: At least once a week. Mo: At least once a month. BiAn: At least once in 6 months. An: At least once a year. < An: Less than once a year
*Statistically significant differences from mean AUC_ord by flossing frequency at α = .05. Contrast: groups being compared. Estimate: estimated difference between flossing frequencies. SE: standard error. df: degrees of freedom
