It is noteworthy to mention the heterogeneity in the significance of the association of nt13708 G/A polymorphism with MS. Such heterogeneity was also observed among previous studies with relative small number of the samples [9], [10][12].
In previous studies, their relative contribution to the total risk may have been concealed by the strong influence of inflammation.
Limitations of previous studies included relative rarity of the disorder which reflected on the small sample size.
will be used throughout the paper to denote the 6 conditions, in accordance with previous studies of relative clause processing (e.g., Caplan, Stanczak, et al. 2008).
Only two previous studies, in relative numbers of persons with diabetes, have examined differences between ethnic groups in South Africa (4, 10).
Sample size was estimated using the WHO formula for sample size to estimate prevalence of alcohol problems (p =0.25 is the prevalence of alcohol problems in previous studies (13 , 15; relative precision = 0.1; significance level = 0.05).
And while direct data comparisons are difficult due to covariance adjustments in our and others data sets, our strength data and genotype data are consistent with previous studies in relative differences between men and women, old and young, and the overall effect of the genotype of one gene (Lynch et al. 1999; Pescatello et al. 2006; Odden et al. 2006).
If this finding was explained only by smoking the HR of lung cancer in the HCV cohort probably should have been higher, as in previous studies the relative risk of lung cancer was ∼10 among smokers compared with non-smokers (Pesch et al, 2012), whereas that for pancreatic cancer was around two-fold (Bosetti et al, 2012).
The previous study compared relative data to Austria with likelihood ratios [3].
In previous studies on Chinese relative clause comprehension, local ambiguities may have rendered a comparison between relative clause types uninterpretable.
