Proportion of children’s liking ratings of the target food (jicama) by the time point and by group (intervention and control). Per GEE analysis, there was a significant difference in liking ratings between study groups at baseline (p = 0.0002) and a significant overall change in liking ratings over time (p = 0.0002), however per interaction analysis the changes over time did not differ between study group (p = 0.1980). Statistically significant differences between follow up times and baseline are indicated by * (p < 0.05) or † (p < 0.001). Y1 = year-one follow up; Y2 = year-two follow up
