Dr. Graham Emslie, a professor of psychiatry at the University of Texas Southwestern Medical Center and the lead investigator on the studies of Prozac that the British regulators found convincing, said that because the studies of different drugs use different measures and are based on significantly varying numbers of subjects, the discrepancies in their findings may mean little.
Several behavioral studies in cats [35] and humans ([36], [37], [38], [39], [40], [41]; but see [42]) have claimed inverse effectiveness, but on different measures and in different conditions than the ones considered here.
Similarly, while the phenotype of interest is depression, different studies may apply different measures and construct regarding "depression", which may cause unavoidable noise in the evaluation process.
Finally, short-term memory has been assessed in four different PCB cohorts with different measures and at different ages.
First, in our study we used different measures and a different time frame than in the study of Winston and colleagues [ 1].
The effect of socio-economic status on the use of health service is not consistent in all studies [ 37, 40, 41], probably owing to the use of different measures and the different financing of health care.
Different characteristics of the samples, different measures and additional variables such as further treatment or social network and support may influence the relationship between major depression and relapse.
New methods for trait analysis combining information from different measures and including different aspects of functioning (such as the range of measures and assessments of the autism/BAP phenotype but also at other levels of investigation including other aspects of behavioral, cognitive styles, ability, and language) will be required.
Previous studies indicate that classifiers' performances in financial risk prediction may vary using different performance measures and under different circumstances.
Further experimentation testing the effects of exogenous and endogenous effects on different behavioural measures and in different task contexts will be required to verify the generalisability of the current findings (c.f., [35], [36]).
