Fig. 1. Energy intake (mean ± SEM) of 46 women at meals in which the
consumption of salad was either ad libitum or fixed, and the timing of consumption
was either before or with the main course of pasta. At one meal, no salad was
served. Among the four salad conditions, different letters for the same meal
component indicate significant differences according to a mixed linear model with
repeated measures (p < 0.036). For the no-salad condition, letters indicate significant
differences from the four salad conditions according to a separate mixed
model with a Dunnett–Hsu adjustment for multiple comparisons (p < 0.012).
