Finally, Le Henanff and associates report on a review of non-inferiority and equivalence trials
published between January 1, 2003, and December 31, 2004.
Additional pre-test trials consisted of 36 combined transitivity and equivalence trials
(18B-C and 18 C-B).
For easy detection of changes within the test, data was divided in three parts with the following number of trials in each test part: test part 1 consisted of seven equivalence trials
, six symmetry trials, and 14 baseline trials; test part 2 consisted of six equivalence trials
, six symmetry trials, and 13 baseline trials; test part 3 consisted of seven equivalence trials
, seven symmetry trials, and 13 baseline trials.
Accuracy on transitivity trials was 10% for the CARO group compared to 85% for the No-CARO group; on equivalence trials
, accuracy was 10.
A second question was whether the pattern of various RTs to trained, symmetry, and equivalence trials
demonstrated the same pattern as reported in previous studies, even with time restrictions.
Although no differences in InvRT or accuracy were found between the groups during testing, a two-way ANOVA showed that, on average, the variance in response speed for participants responding in accord with equivalence could be accounted for by a difference between baseline trials and equivalence trials
(58 %) and a difference between baseline trials and transitivity trials plus equivalence trials
His numbers of correct responses were below the 90 % accuracy criterion on the directly trained trials, symmetry relations, and equivalence trials
96 baseline trials in each component, and 96 stimulus-equivalence trials
in each component), and the restriction that equivalence trials
could not occur in the first component of each component type was removed.
The studies were designed as multi-center, randomized, double-blind, active controlled, equivalence trials
which compared topically applied Cytolex to orally administered ofloxacin, a quinolone antibiotic indicated for skin and soft tissue infections.
When face point to apple"], testing equivalence before symmetry, not mixing equivalence trials
with baseline trials), each of which or in combination could have negatively affected the outcome of the equivalence test (Green, 1990; Holth & Arntzen, 1998; Saunders et al.
Perhaps, these low proportions of equivalence trials
affected the outcome negatively.
Interestingly, when the data for subjects who had failed to produce equivalence were examined, it was found that the most common pattern of responding on all equivalence trials
was "no press.

The test block consisted of 18 symmetry trials and 18 equivalence trials

compared to symmetry trials (e.
