Survival models and their estimation pdf
ShieldSquare CaptchaWhile epidemiologic and clinical research often aims to analyze predictors of specific endpoints, time-to-the-specific-event analysis can be hampered by problems with cause ascertainment. Under typical assumptions of competing risks analysis and missing-data settings , we correct the cause-specific proportional hazards analysis when information on the reliability of diagnosis is available. Our method avoids bias in effect estimates at low cost in variance, thus offering a perspective for better-informed decision-making. The ratio of different cause-specific hazards can be estimated flexibly for this purpose. It thus complements an all-cause analysis.

Metrics details. Time- and dose-to-event phenotypes used in basic science and translational studies are commonly measured imprecisely or incompletely due to limitations of the experimental design or data collection schema. For example, drug-induced toxicities are not reported by the actual time or dose triggering the event, but rather are inferred from the cycle or dose to which the event is attributed.

Although some indication of vaccination effect on the infection-specific hazard is seen, the cycle attribution may be erroneous due to incomplete or missing information, the point estimate shows that the effect on the other-cause-hazard is stronger.
