Sentence examples for shape of the exposure response from inspiring English sources

While the observed pattern persists even after excluding peripheral areas or inaccurately geo-coded addresses, the nature of the study does not permit inferences about the shape of the exposure response function.

However, there are several key methodological challenges in the estimation of the health effects of low-level exposure to air pollution, such as the shape of the exposure response curve, threshold of air pollution, interactive effects of air pollution and weather conditions, and model uncertainty and potential bias.

The shape of the exposure-response relation was examined with a case-control analysis.

Natural cubic splines were incorporated into the Cox models to assess the shape of the exposure-response relationships and allow for possible non-linear effects.

The shape of the exposure-response curve between apparent temperature and log mortality/hospital admission rate was investigated, with a flexible approach, introducing a cubic regression spline for apparent temperature into the model.

Under the assumptions of our analysis, the true number of life-years that would have been saved by enforcing an occupational exposure limit depends on 1) the incidence of the outcome in the study population during follow-up, 2) the distribution of exposure among the cases, and 3) the shape of the exposure-response curve.

The shape of the exposure and response curve is very important.

Unlike previous approaches proposed so far, this method requires less simplification of the exposure-response shape or lag structure.

The results from these two analytic approaches were consistent, indicating that semi-parametric models are valuable and powerful to explore the shape of an exposure-response relationship.

Breaking the exposure into quartiles reduces power, but puts no restrictions on the shape of the exposure-risk relationship.

Using a categorical exposure puts no restrictions on the shape of the exposure-risk relationship, but reduces statistical power.
