“…Finally, sensitivity analyses of the main findings were undertaken using generalized relative risk models for survival data (33), and using a random-effects Cox model originally developed for air pollution research in the CPS-II cohort (18,34). General relative risk models for survival time data were fitted to compare relative risk estimates obtained from linear versus log-linear models using SAS PROC NLP (33) ) with an average value (SD) of 53.5 (38.0) Bq/m 3 .…”

“…We plotted the relationship between PM 2.5 and deaths from all cancers using the natural splines command COXPH in R 3.0.1 with two degrees of freedom. As a sensitivity analysis, we also used models with random effects set at the intercepts to take account of possible intradistrict correlations (25,26).…”

“…We used a hazard model to measure the odds of receiving services over time. A Poisson distribution was used because this approach has been shown to produce similar results to the commonly used Cox proportional hazard (Whitehead, 1980) and has been extended to include random error terms that account for hierarchical data (Ma, Krewski, & Burnett, 2003). A benefit of hazard modeling is its ability to accommodate right censored observations.…”
