^x,yTreatment means with different superscripts differ significantly (P < 0.05) within a row
^aLeast square mean values are reported for treatments: control, without PBLC; PBLC-L, lower dose (80 mg/d) of PBLC; and PBLC-H, higher dose (160 mg/d) of PBLC
^bStandard error of mean
^cContrast: L Linear effect, Q Quadratic effect, and C vs. PBLC Control versus pooled PBLC groups
^dAverage values of last 3-week data
^eMeal length was determined in the last week
^fWeek (P = 0.61) and week × treatment (P = 0.80) effects were not significant
