To propose and evaluate estimates of the censoring distribution as a superior alternative to mean or median follow-up times for quantifying follow-up completeness in survival studies.
Formulated mathematical estimation procedures of censoring distributions tailored for grouped-time (cohort) data.
Developed corresponding estimation techniques applicable to continuous survival data and demonstrated them in an applied setting.
Demonstrated that traditional mean or median follow-up measures systematically distort study completeness in severe conditions where early deaths artificially truncate tracking periods.
Established that modeling censoring distributions directly decouples patient mortality from study observation length, providing an unbiased assessment of follow-up quality.

Implication

Methodological analysis demonstrates that censoring distribution estimates quantify follow-up completeness more reliably than median times, highlighting improved evaluation of survival studies.
