The reference equations currently used in lung function laboratories predicted higher 5 and 5. Normal ranges of 5 and 5 recommended by the equipment manufacturer were clearly different from the ULN/LLN derived from the reference equations. Reference equations of IO indices for Chinese adults from a wide region were provided in this study. It is necessary to update new IO reference equations and adopt ULN/LLN as normal ranges of IO indices. This study was registered at www.clinicaltrials.gov as part of a larger study NCT0346788
