This procedure of careful collection and assessment of data gives strength to the study and minimizes the possibility

of information bias and misclassification of workers in the different quartiles. Furthermore, a study comparing a neurologist’s physical examination to quantitative measurements of tremor disclosed that the latter method provided more precise results (Gerr et al. 2000). All tremor measurements concern postural tremor, and it cannot be entirely ruled out that effects www.selleckchem.com/products/8-bromo-camp.html from HAV exposure could have an impact on some other form of tremor such as, for instance, kinetic tremor or task-specific tremor. Conclusion In the present study, there was no evidence of an exposure–response association between HAV exposure and measured postural tremor. RG-7388 clinical trial Increase in age and nicotine use appeared to be the strongest predictors of tremor.
