Generated Narrative: CodeSystem definition-method

This case-sensitive code system http://hl7.org/fhir/definition-method defines the following codes:

Code	Display	Definition
systematic-assessment	Systematic Assessment	Any method of routinely determining whether or not specific outcomes (e.g. adverse events) have occurred, for example through a standard questionnaire, regular investigator assessment, regular laboratory testing, or other method
non-systematic-assessment	Non-Systematic Assessment	Any non-systematic method for determining whether or not adverse events have occurred, such as self-reporting by participants or occasional assessment/testing
mean	Mean	Aggregated using mean of observed values.
median	Median	Aggregated using median of observed values.
mean-of-mean	Mean of Means	Aggregated using mean of means (e.g. study mean values).
mean-of-median	Mean of Medians	Aggregated using mean of medians (e.g. study median values).
median-of-mean	Median of Means	Aggregated using median of means (e.g. study mean values).
median-of-median	Median of Medians	Aggregated using median of medians (e.g. study median values).
