Kaplan-Meier Analysis of Dental Implant Survival: A Strategy for Estimating Survival with Clustered Observations

摘要: The study's purposes were to estimate dental implant survival in a statistically valid manner and compare three models for estimating survival. We estimated using different statistical models: (1) randomly selecting one per patient; (2) utilizing all implants, assuming independence among implants from the same subject; (3) dependence subject. cohort was composed of 660 patients who had 2286 placed. Due high success rates five-year point standard error estimates varied little models. Patients at risk failure (smokers) manifested greater variation models, 8.2%, 4.0%, 5.6%, respectively. To obtain confidence intervals when performing Kaplan-Meier analyses, we recommend adjusting there are multiple observations within su...
