Among the most discussed issues in the field of pulmonary function testing are reference equations and standardised methods of interpreting pulmonary function test (PFT) results. The Global Lung Function Initiative (GLI) task force gathered information from multiple countries with diverse ethnicities to create a multi-ethnic reference formula suitable for a broad age range. Their first output was the GLI-2012 spirometry reference equations. Together with the GLI-2012 reference equations, the GLI document recommended the use of z-scores to standardise the interpretation of PFT results. Z-scores were introduced as an alternative to per cent predicted and fixed thresholds in interpreting PFTs. After more than a decade, there is still debate on which method of interpretation is better.
肺功能测试领域中讨论最多的问题包括参考方程以及解释肺功能测试（PFT）结果的标准化方法。全球肺功能倡议（GLI）特别工作组收集了来自多个不同种族国家的信息，以创建一个适用于广泛年龄范围的多民族参考公式。其首个成果是GLI - 2012肺量计参考方程。与GLI - 2012参考方程一起，GLI文件推荐使用z分数来标准化PFT结果的解释。在解释PFT时，引入z分数作为预测百分比和固定阈值的替代方法。十多年过去了，关于哪种解释方法更好仍存在争议。
