Statistical analysis was carried out using Rstudio for R V.4.0.3 (R Foundation for Statistical Computing). Using the sum of the left and right PLAs, PA PLA subdivisions were compared with their plethysmographic lung volume equivalent. For example, PLAinsp (that is, total lung area at full inspiration) was compared with TLC, and the difference between PLAinsp and PLAte (inspiratory capacity area) was compared with IC (see online supplemental table 1).
