Using the Bradford Hill evaluation of causality, the current investigation does not support hand-arm vibration as causative of KD.
Exposure science aims to quantify the intensity, frequency, duration, and timing of human contact with chemical, physical, or biological agents occurring in the environment, and may be used to further inform evaluation of causality in the environmental source-to-health outcome continuum (Barr 2006).
The evaluation of the knowledge base on causality, based on expert judgment, was considered to have the highest reliability for PM2.5, SHS, radon, and benzene.
Doubts and criticisms have sometimes been expressed about the relative weights attributed to evidence from individual disciplines to the assessment of cancer hazards to humans; however, each discipline provides important evidence toward the overall evaluation of causality according to the Bradford Hill considerations (Hill 1965).
Other authors [ 7, 8] also pointed out further issues relating to the evaluation of HP: the complexity of the causality between an HP program and its effects, and the unsuitability of the experimental evaluation process for the HP values enshrined in the Ottawa Charter, i.e. the holistic nature of HP interventions and the values of participation, collaboration and empowerment.
25 31 This treatment dramatically changed the gut microbiota and then the metabolic phenotype, suggesting that it could be causal, although demonstration of the causality needs further evaluation in germ-free mice.
The larger trial's quasi-randomized controlled design will ultimately strengthen the evaluation of causality of impact results though no control data is available to evaluate changes in process indicators.
Not having a control group preventing the evaluation of causality.
This long latency adds substantial complexity to the evaluation of causality and assessment of infection control strategies at both a population and individual level.
This could in principle be utilized to help determine whether an mCNV or the sequence variants around it are the true drivers of an association signal a scientific opportunity that is not possible with most SNPs and bi-allelic CNVs, which often have near perfect linkage disequilibrium (LD) with many other variants that hinders fine-mapping and the evaluation of causality.
