We did not find any significant effect modification between socioeconomic factors and disease-related factors (data not shown).
None of the other ISAAC studies investigated effect modification between these two factors.
There was no evidence for modification of the association between factors of exposure and child weight status by child's sex, maternal prepregnancy BMI, maternal socioeconomic class and maternal smoking status (p-values for interaction > 0.2; data not shown).
Although one-to-one modification between a transcription factor and its binding affinity is a convenient explanation of our observations, it is possible that the mechanisms underlying regulatory motif modification may be more complex in some cases.
We observed a considerable effect modification between the most important factors predicting anal sphincter injuries in the active second stage of labour.
Prior to that, every possible effect modification between the proposed risk factors and the confounders was examined, but all interaction terms were not statistical significant (p-values > 0.05).
Tables 2 and 3 show the difference in demographics, glycemic control, and cardiovascular risk factor modification between patients with type 1 and type 2 diabetes.
Logistic regression modeling was performed to examine potential effect modification factors between work environmental factors and other variables in relation to the risk of MDD.
In separate analyses, we assessed potential effect modification between maternal height and cardiovascular risk factors, but found no consistent evidence of any interaction (all P-values above 0.10, except for HDL cholesterol with p=0.03) (results not shown).
This study explores whether there is any effect modification between lead exposure and key sociodemographic factors on IQ [measured using the Wechsler Intelligence Scales for Children-Revised (WISC-R) instrument] at 11 13 years of age.
