+
+### Dataset Summary
+
+**PMC-Patients** is a first-of-its-kind dataset consisting of 167k patient summaries extracted from case reports in PubMed Central (PMC), 3.1M patient-article relevance and 293k patient-patient similarity annotations defined by PubMed citation graph.
+
+
+### Supported Tasks and Leaderboards
+
+**This is purely the patient summary dataset with relational annotations. For ReCDS benchmark, refer to [this dataset](https://huggingface.co/datasets/zhengyun21/PMC-Patients-ReCDS)**
+
+Based on PMC-Patients, we define two tasks to benchmark Retrieval-based Clinical Decision Support (ReCDS) systems: Patient-to-Article Retrieval (PAR) and Patient-to-Patient Retrieval (PPR). 
+For details, please refer to [our paper](https://arxiv.org/pdf/2202.13876.pdf) and [leaderboard](https://pmc-patients.github.io/).

+## Dataset Structure
+
+### PMC-Paitents_full.json
+
+This file contains all information about patients summaries in PMC-Patients, which is a list of dict with keys:
+
+- `patient_id`: string. A continuous id of patients, starting from 0.
+- `patient_uid`: string. Unique ID for each patient, with format PMID-x, where PMID is the PubMed Identifier of the source article of the patient and x denotes index of the patient in source article.
+- `PMID`: string. PMID for source article.
+- `file_path`: string. File path of xml file of source article.
+- `title`: string. Source article title.
+- `patient`: string. Patient summary.
+- `age`: list of tuples. Each entry is in format `(value, unit)` where value is a float number and unit is in 'year', 'month', 'week', 'day' and 'hour' indicating age unit. For example, `[[1.0, 'year'], [2.0, 'month']]` indicating the patient is a one-year- and two-month-old infant.
+- `gender`: 'M' or 'F'. Male or Female.
+- `similar_patients`: list of string. `patient_uid` of the similar patients.
+- `relevant_articles`: list of string. `PMID` of the relevant articles.
