All subjects underwent PFTs one week after each HRCT examination using Cosmed Quark PFT (Cosmed, Rome, Italy) and SensorMedics Vmax 229 (SensorMedics Co., Yorba Linda, CA, USA). The measurements made were set to meet the ATS/ERS instrument quality control standards. We measured the total lung capacity (TLC), residual volume (RV), RV/TLC (%), forced expiratory volume in 1 second/forced vital capacity [FEV1/FVC (%)], FEV1 (% pred), FVC (% pred), peak expiratory flow (PEF) (% pred), maximum expiratory flow (MEF) (% pred), forced expiratory flow (FEF)25% (% pred), FEF50% (% pred), FEV1 (% pred) after treatment, and FEV1/FVC (%) after treatment.

Standard pulmonary-function tests including spirometry and measurements of DLCO (Sensormedics Vmax 229, Sensormedics Corp, CA, USA) were undertaken and results were compared to normative values [33 (link), 34 (link)]. Predicted maximal voluntary ventilation (MVV) was calculated by multiplying FEV₁ by 40 [35 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
