It is challenging to relate outcome success to program characteristics given the variability of the programs.
Intra- and inter-observer accuracy and variability of the software program using this HRCT technique in phantoms, consisting of rigid tubes to measure known areas, has been previously shown by us [15] and by others [17] to be highly resistant to operator bias.
To identify the effects of this intervention the authors took advantage of the geographic variability in implementation of the program that started in 2000 some states were treated but neighboring states were not.
To include more articles, eligibility criteria would have had to be broader, but increasing the variability of the analysed treatment programs, for instance by including prevention programs, would have lead to even less comparability of results.
In addition to variability in the program approaches, there was a large variability in evaluation approaches.
The objective of this study was to describe a program evaluation system that can be applied to a wide range of quality of life (QOL) programs in the Navy specific enough to capture the variability of several QOL programs with sufficient consistency across programs to facilitate multi-program comparisons.
It is difficult to determine what program model is best given the variability of program and local contexts.
The new 2014 to 2018 SCOSTEP program Variability of the Sun and Its Terrestrial Impact (VarSITI) will focus on the unusual low solar activity during solar cycle 24 and its consequences on Earth.
However, comparison across studies highlighted wide variability of CR program design and delivery.
Thus the participants with subthreshold depression had already responded well to the initial behavior therapy interventions and there was not much variability left throughout the latter half of the program (floor effect).
