Multivariable Cox Regression Analysis of Platelet Nadir and 28-Day Mortality

A statistical analysis dataset examining the association between platelet nadir groups and 28-day all-cause mortality using multivariable Cox regression. The dataset is a 5.5 KB XLS file authored by Jianchun Wei and last updated on May 6, 2026. It is shared under a CC-BY-4.0 license on the figshare platform.

Use Cases

• Validate the prognostic value of platelet nadir for 28-day mortality based on the described Cox regression analysis.
• Reproduce or extend the multivariable survival analysis described in the dataset.
• Benchmark new mortality prediction models against the established association between platelet levels and outcome.
• Teach or demonstrate the application of Cox regression in a clinical research setting.

Strengths

• Dataset is openly licensed under CC-BY-4.0, permitting broad reuse.
• File size is precisely known at 5.5 KB, indicating a focused analysis.
• Author and specific last update timestamp (2026-05-06 17:33:08) are provided.

Limitations
