Owing to the effects of intraindividual variation, estimating workers' exposures from a few measurements can attenuate measures of effect.
A central finding from the present analysis was that school-based pollutant measurements generally provided the strongest measures of effect.
Measures of effect (assessment endpoints) should be established that represent measurable changes relevant to the risk characterization.
This effectiveness has not necessarily translated into a favorable impact on clinical measures of effect or on medication adherence.
Olejnik, S. & Algina, J. Generalized eta and omega squared statistics: measures of effect size for some common research designs.
These problems include the use of retrospective power calculations and standardized measures of effect size.
This article describes procedures for presenting standardized measures of effect size when contrasts are used to ask focused questions of data.
Included are robust measures of effect size and two-stage techniques for controlling the length of confidence intervals.
This is particularly worrisome, because the measures of effect on depression or anxiety tend to be subjective, Goodwin says.
This was a controlled study consisting of baseline observation, intervention and follow-up observation using the same measures of effect.
Shorter clinical trials are cheaper for industry but frequently rely on measures of effect called surrogate endpoints that can be unreliable predictors of ultimate outcome and do not necessarily correlate with benefits for patients.
