This code system http://terminology.hl7.org/CodeSystem/synthesis-type defines the following codes:

Code	Display	Definition
std-MA	summary data meta-analysis	A meta-analysis of the summary data of estimates from individual studies or data sets.
IPD-MA	individual patient data meta-analysis	A meta-analysis of the individual participant data from individual studies or data sets.
indirect-NMA	indirect network meta-analysis	An indirect meta-analysis derived from 2 or more direct comparisons in a network meta-analysis.
combined-NMA	combined direct plus indirect network meta-analysis	An composite meta-analysis derived from direct comparisons and indirect comparisons in a network meta-analysis.
range	range of results	A range of results across a body of evidence.
classification	classifcation of results	An approach describing a body of evidence by categorically classifying individual studies (eg 3 studies showed beneft and 2 studied found no effect).
pooled	pooled rates	An unweighted average.
