This trial was designed to test the exercise-training modalities for noninferiority, with the key secondary objective of testing for superiority with respect to the OUES. The inclusion criterion was having stable CAD diagnosed by coronary angiography.
The OUES was assessed based on the respiratory data during exercise by calculating the slope of the linear relationship between V[O.sub.2] (y-axis) and the logarithm of VE (x-axis) using single regression analysis.
Two-way analysis of variance (ANOVA) with repeated measures was performed to test for possible within-group and between-group differences in physical characteristics, cardiorespiratory parameters, and the OUES. When significant differences were detected, Tukey's post hoc comparisons were performed.
For the CET group, the sample size of 18 provided the power (96%) to detect a difference in OUES based on a relevant difference of 0.32 L/min, an SD of 0.35 L/min, [alpha]=0.05, and a two-tailed test of significance.
In addition, no statistically significant differences in pre-intervention OUES were present (Table 2).
The OUES values were similarly and significantly increased from baseline in both the CET and IET groups after the exercise-training program (Table 2).

Ventilatory efficiency and the OUES are commonly measured using standardised treadmill protocols and/or stationary ergometers; however, limited data report any differences in slope calculation when different ergometers are used.
The slope constant of this regression line was used as the measure of oxygen uptake efficiency (OUES).
[VCO.sub.2]), oxygen uptake efficiency slope (OUES), and maximum oxygen uptake ([VO.sub.2]max), in 12 trained endurance athletes.
The main findings of this study were: firstly, that for the group, the slope of the linear relationship between VE and [VCO.sub.2] was not different when different ergometers were used; and secondly, that for the group, the OUES and [VO.sub.2]max were higher when tests were performed on a cycle ergometer compared to either a treadmill or rowing ergometer.
The OUES may become more reliable when calculated from data obtained from higher levels of exercise intensity (23) however the OUES differs little when calculated only from data up to 75% of a maximal test (7), (24).
