Serum Creatine Kinase and Mortality in Chinese Centenarians, 2014-2016

Chinese centenarians residing in the community were followed between June 2014 and December 2016 to study the association between serum creatine kinase levels and all-cause mortality. The prospective cohort study included 949 participants followed for a median of 29.4 months, with mortality analyzed using restricted cubic spline and Cox regression methods. The dataset, authored by Xinyan Gong and shared under a CC-BY-4.0 license, presents the results of this analysis.

Use Cases

• Modeling all-cause mortality risk based on serum creatine kinase levels.
• Investigating the inverse J-shaped relationship between a biomarker and survival in extreme old age.
• Conducting subgroup analyses of mortality risk factors in a centenarian population.
• Benchmarking survival analysis techniques like restricted cubic spline and Cox regression on a specific demographic cohort.

Strengths

• Dataset is based on a clearly defined cohort of 949 centenarians.
• Study includes a median follow-up period of 29.4 months with detailed mortality outcome tracking.
• Analysis employs multiple statistical methods (RCS, Cox regression, Kaplan-Meier) as described.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific cohort in China.
