no residual confounding, no confounding by other variables, noinformation bias or no selection bias.6.Test the hypothesis that job strain does not modify the associationbetween mechanical exposure and the 1-y CI of neck or shoulderpain on the additive scale.H0: There is no effect measure modification of the associationbetween exposure and the 1-y cumulative incidence of pain acrossthe strata of job strain on the additive scale.HA: There is an effect measure modification of association betweenexposure and CI of pain across the strata of job pain on the additivescale.H=[0.06480.0653]20.000202+[0.06780.0653]20.001057=0.00124+0.00586=0.0071P[x^2 > 0.0071] > 0.05We fail to reject the null hypothesis at 0.05 level of significance. Weconclude that there is no effect measure modification by job strain onthe additive scale for the association between exposure and the 1-ycumulative incidence of shoulder pain assuming. No confounding, noselection bias, or information bias.
