Background
The Global Lung Function Initiative attempted to formulate global all‐age lung function equations. The suitability of these equations to Middle Eastern children was never evaluated; this study will evaluate these equations in addition to other regional ones.
Methods
Spirometry was conducted for 582 (311 boys) healthy 6‐ to 13‐year‐old Jordanian children. z scores, predicted values, percent predicted values, and frequency of records below lower limit than normal (LLN) were calculated for each child using the studied equations.
Results
Although none of the studied equations produced a perfect representation of the study data, the GLI 2012 equations for Caucasians were the most suitable.
Conclusion
GLI 2012 equations for Caucasians are a reasonable fit for Jordanian school‐aged children.
