Headache and Gastrointestinal (GI) Symptoms VAS results from the interaction effect between eating condition and time of night (line graphs), and the total mean change from 21:00 to 5:00 (bar graphs). Black lines with black markers and the black columns represent the Meal at Night condition (MN), black lines with grey markers and the grey columns represent the Snack at Night condition (SN), dashed lines with white markers and the white columns indicate the No Eating at Night condition (NE). The vertical black line on each line graph indicates when the meal or snack was consumed. The grey shaded horizontal line on each line graph indicates the midpoint of each VAS. Means presented are estimated marginal means, and error bars indicate standard errors from model estimates. (* p < 0.05).
