Answer 1

41)The effect is influenced by effect modifications

When there is no relation between the exposure and the disease and depens on a third variable .Here the exposure has different impact in different exposure

Here exposure is independent variable and disease and independent variable

The confounding variable are one which has an effect on the dependent variable that has disease because of the exposure.
