🗺 **What is OMOP2OBO?** 

-----------------------------------------------------------------------

*Motivation*  

- A significant promise of electronic health records (EHRs) lies in the ability to perform large-scale investigations of mechanistic drivers of complex diseases. Despite significant progress in biomarker discovery, this promise remains largely aspirational ([`PMID:32335224`](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7179504/), [`PMID:30304648`](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6503847/)). 
- Linking molecular data to clinical data stored in EHR data will support biologically meaningful analyses, and can be achieved by integrating knowledge about biology and pathophysiology from multiple ontologies.  
- Similar to clinical terminologies, computational ontologies are classification systems that provide detailed representations of a specific domain of knowledge consisting of a set of concepts and logically defined relationships. Unlike most clinical terminologies, ontologies are computable and interoperable, which means they can be logically verified using description logics and easily integrated with other ontologies and non-ontological data including data from basic science and clinical research ([`PMID:30304648`](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6503847/)).
- The usefulness of normalizing (i.e. mapping or annotating) clinical data to ontologies, like those in the Open Biological and Biomedical Ontologies ([OBO](http://www.obofoundry.org/)) Foundry, has been recognized as a fundamental need for the future of deep phenotyping ([`PMID:32335224`](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7179504/)).  
- Existing work has largely been limited to using ontologies to improve phenotyping in specific diseases (i.e. infectious [[`PMID:31160594`](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6546783/)] and rare diseases [[`PMID:31231902`](https://pubmed.ncbi.nlm.nih.gov/31231902/)]) and for the enhancement of specific biological and clinical domains (e.g. laboratory tests [[`PMID:31119199`](https://pubmed.ncbi.nlm.nih.gov/31119199/)] and diagnoses [[`PMID:29295235`](https://pubmed.ncbi.nlm.nih.gov/29295235/)]).  
- Unfortunately, learning algorithms are not yet able to capture the complex clinical and biological semantics underlying these concepts and their relationships. Until a comprehensive, robust resource that includes mappings between multiple clinical domains and biomedical ontologies is created and validated, automatic generation of inference between patient-level clinical observations and biological knowledge will not be possible. 

*Objective*  
We developed `OMOP2OBO`, the first health system-wide integration and alignment between the Observational Health Data Sciences and Informatics' Observational Medical Outcomes Partnership ([OMOP](https://www.ohdsi.org/data-standardization/)) standardized clinical terminologies and eight OBO biomedical ontologies spanning diseases, phenotypes, anatomical entities, cell types, organisms, chemicals, metabolites, hormones, vaccines, and proteins.

knitr::include_graphics("https://user-images.githubusercontent.com/8030363/182207267-f674e6c0-af16-4b94-bdc1-45ddea43a7f7.png")
```
</div>

<br><br> 

-----------------------------------------------------------------------

🤔 **Mappings Overview**

-----------------------------------------------------------------------

Each mapping file contains several tabs:  

- For the Drug ingredient and measurement files, the first tab will contain extended information on the `OMOP` clinical terminologies that were used to create the mappings.   
- The condition mapping data file contains a similar, but less extensive set of data, which is present within each ontology tab. For all files the remaining tabs containing the results from mapping to a specific ontology. For conditions, symptoms were aligned to the [`Human Phenotype Ontology (HPO)`](https://hpo.jax.org/) and diagnoses were aligned to the [`Mondo Disease Ontology (Mondo)`](http://mondo.monarchinitiative.org/).  
- For drug ingredients, all concepts were aligned to at least one [`Chemical Entities of Biological Interest (ChEBI)`](https://www.ebi.ac.uk/chebi/) concept and the remaining ontologies ([`National Center for Biotechnology Information Taxon Ontology (NCBITaxon)`](https://www.ncbi.nlm.nih.gov/taxonomy), [`Protein Ontology (PR)`](https://proconsortium.org/), and [`Vaccine Ontology (VO)`](https://obofoundry.org/ontology/vo.html)) were mapped by their drug class and/or type (e.g., biologics versus vaccines).  
- For each measurement, all levels of the test result (results above, below, and within a reference range) were mapped, not only those deemed clinically relevant. Results outside of a reference range, but not currently deemed clinically relevant (as advised by the literature or consultation via domain expert), were annotated to the nearest relevant ontology concept ancestor. The interpreted measurement result was mapped to the `HPO`, the measurement substance (body fluids, tissues, and organs via the [`Uber Anatomy Ontology (Uberon)`](https://uberon.github.io/), the entity being measured (chemicals, metabolites, or hormones via `ChEBI`; cell types via the [`Cell Ontology (CL)`](https://obofoundry.org/ontology/cl.html); and proteins and protein complexes via `PR)`, and the species of the measured entities (organism taxonomy via `NCBITaxon`).  

The figure below provides an example of a `OMOP2OBO` mapping to an `OMOP` condition concept. This figure is include to provide detail into the different components that are included in each mapping.

```
</div>

<br><br>

-----------------------------------------------------------------------

✅ **Mapping Verification and Validation** 

-----------------------------------------------------------------------

To verify that the mappings are both clinically and biologically meaningful, we have performed extensive experiments to verify the [accuracy](https://github.com/callahantiff/OMOP2OBO/wiki/Accuracy), [generalizability](https://github.com/callahantiff/OMOP2OBO/wiki/Generalizability), and [logical consistency](https://github.com/callahantiff/OMOP2OBO/wiki/Consistency) of each released mapping set. Please note that the consistency experiments are still in progressand have only been applied to the `HPO` and `MONDO` mappings at this time.
