WebThe GLI-2012 are multi-ethnic reference equations for spirometry for the 3–95-yr age range. 8 GLI-2012 were developed for four specific populations: Caucasian, Black, North-East Asian and South-East Asian and were intended to be applied globally. 8 Previous studies showed that the applicability of GLI-2012 was different in different countries ... Web∘ The Global Lung Function Initiative (GLI)-2012 multiethnic spirometry reference values are recommended for use in North America and elsewhere for the ethnic groups represented. Their smooth continuity throughout growth is advantageous for laboratories testing children or adolescents.
