In Table 2 of the above-listed article, the two column headings “Ghrelin” should be “Saline”, and the two column headings “Saline” should be “Ghrelin”. The correct table appears below.

Data are means ± SE. M1 latency is the latency to the onset of the first nocturnal meal; M1 size and M2 size are the sizes of the first and second nocturnal meals, respectively; M1–2 IMI is the interval between these meals; 2-h food intake (g) is the cumulative food intake during the first 2 h of the dark phase; and 2-h meal no. is the number of meals begun during these 2 h. ANOVA revealed a significant interaction (estradiol × ghrelin) effect for M1 latency (F1,26 = 4.92); a significant main effect of ghrelin for 2-h food intake (F1,26 = 3.57); and significant main effects of estradiol for M1 size (F1,26 = 10.54), M1–2 IMI (F1,26 = 12.38), M2 size (F1,26 = 8.35), and 2-h meal no. (F1,26 = 6.87).
Significant difference between ghrelin and saline injection values in vehicle-treated rats (Bonferroni test, P < 0.05);
significant difference between saline values in vehicle-treated and in estradiol-treated rats (Bonferroni test, P < 0.05).
