BackgroundClinical data is instrumental to medical research, machine learning (ML) model development, and advancing surgical care, but access is often constrained by privacy regulations and missing data. Synthetic data offers a promising solution to preserve privacy while enabling broader data access. Recent advances in large language models (LLMs) provide an opportunity to generate synthetic data with reduced reliance on domain expertise, computational resources, and pre-training.ObjectiveThis study aims to assess the feasibility of generating realistic tabular clinical data with OpenAI’s GPT-4o using zero-shot prompting, and evaluate the fidelity of LLM-generated data by comparing its statistical properties to the Vital Signs DataBase (VitalDB), a real-world open-source perioperative dataset.MethodsIn Phase 1, GPT-4o was prompted to generate a dataset with qualitative descriptions of 13 clinical parameters. The resultant data was assessed for general errors, plausibility of outputs, and cross-verification of related parameters. In Phase 2, GPT-4o was prompted to generate a dataset using descriptive statistics of the VitalDB dataset. Fidelity was assessed using two-sample t-tests, two-sample proportion tests, and 95% confidence interval (CI) overlap.ResultsIn Phase 1, GPT-4o generated a complete and structured dataset comprising 6,166 case files. The dataset was plausible in range and correctly calculated body mass index for all case files based on respective heights and weights. Statistical comparison between the LLM-generated datasets and VitalDB revealed that Phase 2 data achieved significant fidelity. Phase 2 data demonstrated statistical similarity in 12/13 (92.31%) parameters, whereby no statistically significant differences were observed in 6/6 (100.0%) categorical/binary and 6/7 (85.71%) continuous parameters. Overlap of 95% CIs were observed in 6/7 (85.71%) continuous parameters.ConclusionZero-shot prompting with GPT-4o can generate realistic tabular synthetic datasets, which can replicate key statistical properties of real-world perioperative data. This study highlights the potential of LLMs as a novel and accessible modality for synthetic data generation, which may address critical barriers in clinical data access and eliminate the need for technical expertise, extensive computational resources, and pre-training. Further research is warranted to enhance fidelity and investigate the use of LLMs to amplify and augment datasets, preserve multivariate relationships, and train robust ML models.

The generation process involves two steps, namely the synthesis of the main data (cohort info, baseline variables, annual PM_2.5 exposure) and then the sampling of death events. The R scripts for performing the data synthesis are provided in the GitHub repo (subfolder Rcode/synthcode).

The first part merges all the data, including the annual PM_2.5 levels, into a single wide-format dataset (with a row for each subject), generates a synthetic version, adds fake IDs, and then extracts (and reshapes) the single datasets. In the second part, a Cox proportional hazard model is fitted on the original data to estimate risks associated with various predictors (including the main exposure represented by PM_2.5), and then these relationships are used to simulate death events in each year. Details on the modelling aspects are provided in the article.

This process guarantees that the synthetic data do not hold specific information about the original records, thus preserving confidentiality. At the same time, the multivariate distribution and correlation across variables, as well as the mortality risks, resemble those of the original data, so the results of descriptive and inferential analyses are similar to those in the original assessments. However, as noted above, the data are used only for illustrative purposes, and they must not be used to test other research hypotheses.

Natural Language Processing can help to unlock knowledge in the vast troves of unstructured clinical data that are collected during patient care. Patient confidentiality presents a barrier to the sharing and analysis of such data, however, meaning that only small, fragmented and sequestered datasets are available for research. To help side-step this roadblock, we explore the use of Transformer models for the generation of synthetic notes. We demonstrate how models trained on notes from the MIMIC-III clinical database can be used to generate synthetic data with potential to support downstream research studies. We release these trained models to the research community to stimulate further research in this area.

📂 Folder Structure

/
├── synthetic_images/   # Synthetic images (.png)
├── synthetic_labels/   # YOLO format labels (.txt)
├── synthetic_xml_labels/ # Pascal VOC format labels (.xml)

Each image has corresponding .txt and .xml files with the same filename.

📏 Annotation Formats

• YOLO Format (.txt):
  Each line represents a word, with format: class_id center_x center_y width height All values are normalized between 0 and 1.
  Example: 0 0.235 0.051 0.144 0.081

• Pascal VOC Format (.xml):
  Standard XML structure containing image metadata and bounding box coordinates (absolute pixel values).
  Example: ```xml

🖼️ Image Samples

Each image contains random Khmer words placed naturally over backgrounds, with different font styles, sizes, and visual effects.
The dataset was carefully generated to simulate real-world challenges like:

• Different lighting conditions
• Different text sizes
• Motion blur and color variations

🧠 Use Cases

• Train YOLOv5, YOLOv8, EfficientDet, and other object detection models.
• Fine-tune OCR (Optical Character Recognition) systems for Khmer language.
• Research on low-resource language computer vision tasks.
• Data augmentation for scene text detection.

⚙️ How It Was Generated

1. A random real-world background or random color is chosen.
2. Random Khmer words are selected from a large cleaned text file.
3. Words are rendered with random font, size, color, spacing, and position.
4. Image effects like motion blur and color jitter are randomly applied.
5. Bounding boxes are automatically generated for each word.

🧹 Data Cleaning

• Words were sourced from a cleaned Khmer corpus to avoid duplicates and garbage data.
• Fonts were tested to make sure they render Khmer characters properly.

📢 Important Notes

• This dataset is synthetic. While it simulates real-world conditions, it may not fully replace real-world labeled data for final model evaluation.
• All labels assume one class only (i.e., "word" = class_id 0).

❤️ Credits

• Khmer text data collected from open-source projects such as khmer-text-data.
• Khmer fonts collected from free and open repositories like Khmer Fonts Project.

📈 Future Updates

We plan to release:

• Datasets with rotated bounding boxes for detecting skewed text.
• More realistic mixing of real-world backgrounds and synthetic text.
• Advanced distortions (e.g., handwriting-like simulation).

Stay tuned!
