Individual Participant Data from an Esophageal Cancer Surgery Oxygen Therapy Trial

A randomized controlled trial of 100 patients after esophageal cancer surgery, comparing high-flow nasal cannula oxygen therapy to conventional oxygen therapy in the post-anesthesia care unit. The dataset includes primary outcomes of lung ultrasound scores at three time points and secondary measures like PaO2/FiO2 ratios and pulmonary complication incidence. The data was uploaded by Liye Han to figshare and last updated on 2026-05-05.

Use Cases

• Compare lung ultrasound score trajectories between intervention groups based on the three measurement time points (T1, T2, T3).
• Analyze the relationship between oxygen therapy type and PaO2/FiO2 ratios based on the secondary outcome measures.
• Model the risk of hypoxemia or 7-day pulmonary complications based on treatment group and other patient factors likely present in the data.
• Replicate the statistical analysis of the primary and secondary outcomes described in the trial results.

Strengths

• Data originates from a randomized controlled trial with 100 participants, providing a structured experimental design.
• Includes specific, quantified primary outcomes such as mean changes in lung ultrasound scores (e.g., -5.6 points for HFNC group).
• Contains detailed secondary outcome measures like PaO2/FiO2 ratios (e.g., 340 ± 32 mmHg) and incidence rates (e.g., 10.0% complications).

Limitations

• Row count is unknown, which may limit suitability assessment for certain modeling tasks.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small at 38.1 KB, indicating a limited scope focused on a specific clinical trial.
