Other researchers hypothesized that DSR of nests would be lower in the early stages of incubation because vulnerable nests would be depredated earlier (Klett and Johnson 1982; Coates and Delehanty 2010); thus, we incorporated a time-dependent covariate (e.g., nest age) into models.
Using Cox proportional hazards modeling that incorporated transfusion as a time-dependent covariate, transfusion was associated with an increased hazard for 30-day death (adjusted hazard ratio [HR], 3.94; 95% confidence interval [CI], 3.26-4.75) and 30-day death/MI (HR, 2.92; 95% CI, 2.55-3.35).
The association between transfusion and outcome was assessed using Cox proportional hazards modeling that incorporated transfusion as a time-dependent covariate and the propensity to receive blood, and a landmark analysis.Thirty-day mortality.Of the patients included, 2401 (10.0%) underwent at least 1 blood transfusion during their hospitalization.
The association between transfusion and outcome was assessed using Cox proportional hazards modeling that incorporated transfusion as a time-dependent covariate and the propensity to receive blood, and a landmark analysis.
Using Cox proportional hazards modeling that incorporated transfusion as a time-dependent covariate and adjusted for baseline characteristics, bleeding, transfusion propensity, and nadir hematocrit, transfusion was associated with an increased hazard for 30-day death (adjusted hazard ratio [HR], 3.94; 95% confidence interval [CI], 3.26 4.75) and 30-day death/MI (HR, 2.92; 95% CI, 2.55 3.35).
However, because the risk of delirium onset is likely to vary over the course of admission to an intensive care unit depending on the evolution of disease severity, we also incorporated time dependent variables in our primary analysis (fig 1).
The tool acis_process_events includes a time-dependent gain (TGAIN) adjustment.
So, scour is a time-dependent hazard.
A time-dependent failure tree is developed.
a Time-dependent photocatalytic degradation of RhB.
Considering a time-dependent magnetic field (37).
