The kernel densities for the distribution of logHR estimates for fruits and vegetable intake per 100 g per day (\( {\widehat{\beta}}_{T1} \), left panel) and for the number of cigarettes smoked per day (\( {\widehat{\beta}}_{T2} \), right panel) adjusted for the bias with the multivariate method. The dotted vertical line indicates the means of unadjusted logHR estimates; the solid vertical lines indicate the means of logHR estimates adjusted for the bias
