To date, implementation of these alternative viral load assays remains limited in resource constrained settings due to their cost (e.g., US$300 for ExaVir Load and US$200 for the Generic HIV-1 viral load from Biocentric) [ 12], absence of FDA-approval, lack of comparability with existing VL gold standards, and so forth.
Finally the absence of blinding can distort the comparability of the groups regarding study withdrawal or patients' adherence, since patients participating in a non-inferiority trial may prefer to receive the simpler therapy.
Briefly, the NOS allots a maximum of nine points based on the representativeness of the intervention and control groups, ascertainment of intervention, absence of outcomes at study start, comparability of groups based on study design and analysis, blinded assessment/record linkage to confirm outcomes, sufficient length of follow-up and sufficiently low withdrawal rate.
Each firm's pay ratio also presents a challenge of interpretation, and hence comprehensibility, because of the absence of objective pay ratio benchmarks and the lack of comparability among different firms' ratios.
An absence of useful metrics, shared standards and comparability slows progress and calls into question the efficacy of corporate sustainability at a time when environmental challenges have never been more acute.
While health care decision-makers increasingly recognize indirect treatment comparisons as an acceptable alternative method of comparison in the absence of real-world parallel-group data, differences in study populations may limit their comparability.
Finally, there is the issue of comparability.
Even into the eighteenth, points of comparability can be found.
Hard to understand how this meets any reasonable definition of comparability of effort.
Given the lack of comparability, it's almost surprising that anyone outsources today.
Given the lack of comparability across companies, it's almost surprising that anyone outsources.
