Baseline Characteristics Before and After PSM for CffDNA and PTB Association

A small dataset of 13.5 KB in XLS format contains baseline characteristics for a study on the association between cell-free fetal DNA (CffDNA) and preterm birth (PTB). It includes data before and after propensity score matching (PSM). The dataset was authored by Xiaosa Wang and last updated on May 11, 2026.

Use Cases

• Evaluate the effectiveness of propensity score matching based on the before-and-after comparison structure.
• Analyze the association between a fetal biomarker (CffDNA) and a clinical outcome (PTB) using matched cohort data.
• Benchmark statistical matching methods in perinatal epidemiology based on the described baseline characteristics.

Strengths

• Dataset is openly licensed under CC-BY-4.0.
• File size is precisely 13.5 KB.
• Last update timestamp is provided (2026-05-11 17:29:29).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
