Description

Reference table for thresholds of clinical significance for anesthetic gases (halogenated and nitrous).

Limitation

Not a phenotype. Reference Table only.

Data quality is limited to individual site documentation accuracy, completeness, and variable mapping, which is performed by each site, independently. MPOG, as the coordinating center, reviews data quality at each data upload and monthly via Data Diagnostics and Case Validation tools. This review, while thorough, may not contain all data elements relevant to this phenotype and thus should be carefully reviewed by the user.
