OBJECTIVE —To use various cialis and number of eerections models to estimate the risk of mortality from lung cancer due to occupational exposure to respirable crystalline silica dust. Internal and external adjustments were used to control for potential confounding from the effects of time since first observation, calendar time, age, and Hispanic ethnicity.
Cubic smoothing spline models were used to assess the fit of the models. Evaluations of the fit of the models were performed by comparing their deviances.
For those who died of lung cancer the linear relative rate model predicted rate ratios for mortality from lung cancer of about 1. The predicted number of deaths crystalline silica and lung cancer lung cancer suggests that current occupational health standards may not be adequately protecting workers from the risk of lung cancer.
