In addition, if all caregivers who would have sought care on a day prior to the mobile clinic's visit did so on the day of the visit (and whose careseeking behaviour was therefore a cumulative time-dependent probability), the mobile clinic would reduce mortality by 0.17 deaths per 10,000 child-days (CI: 0.15 to 0.19) and achieve a 32.8% reduction in pneumonia-specific mortality.
Models were fit using Cox regression, in which each case was compared with its matched risk set (with matching based on white or nonwhite race), cumulative exposure was time dependent, and the time variable was age.
Main outcome measure Risk of breast cancer estimated with a weighted Cox proportional hazards model with a time dependent individually estimated cumulative breast dose, based on nominal estimates of organ dose and frequency of self reported diagnostic procedures.
The predictions based on the two approaches were investigated using time dependent ROC curves for cumulative PFS.
Therefore, for each cancer, we used multivariate Poisson regression to compute incidence rate ratios with 95% confidence intervals comparing incidence during each period, with adjustment for current age (time dependent, single years), sex, and the cumulative duration of transplant function (time dependent, years).
These toxic activities and changes are both dose and time dependent resulting from its quantity and cumulative impact.
The sensitivity and specificity of the REGS classifiers and predictors were investigated using time dependent receiver operating characteristics (ROC) curves for cumulative PFS and OS.
Analysis is aided by a recent time dependent analytical waterflood performance model with respect to cumulative injected water for adequate economic analysis.
Previously we have shown that there are marked differences in the cumulative time spent in custody among Indigenous and non-Indigenous opioid-dependent people [ 48].
When there are multiple time-dependent coefficients, interpreting the time dependent hazard ratios can be difficult in the log cumulative hazard framework of the Royston-Parmar models [ 20].
