Fig. 2. Within-record comparisons of respiratory quotients (averages of the first,
second and third hour of recording) in the first repetition (A), second
repetition (B) and third repetition (C) (means ± s.e.m.; A,
N=19; B, N=17; C, N=13). Differences were
marginally significant in the first measurement
(F2,36=2.9; P=0.068; repeated-measures ANOVA),
significant in the second measurement (F2,34=8.10;
P=0.0013; repeated-measures ANOVA) and non significant in the third
measurement (F2,24=2.61; P=0.094;
repeated-measures ANOVA). After pooling repetitions, the comparison became
highly significant (F2,98=10.48; P=0.0001;
repeated-measures ANOVA).
