From: Predictors of lung function decline in scleroderma-related interstitial lung disease based on high-resolution computed tomography: implications for cohort enrichment in systemic sclerosis–associated interstitial lung disease trials

Fig. 1

Absolute changes in percentage of predicted forced vital capacity (FVC%) determined using different high-resolution computed tomography (HRCT) staging systems. Data are shown as box plots. Each box represents the interquartile range (IQR), indicating the first (25th percentile) and third (75th percentile) quartiles. Lines inside the boxes represent the medians. Whiskers represent 1.5 times the upper and lower IQRs. Circles indicate outliers. p Value is based on two-samples t test. a Visual semiquantitative fibrosis score. b Goh and Wells unadjusted stratification. c Quantitative assessment of total extent of interstitial lung disease (QILD) in whole lung. d Quantitative percentage with fibrosis (QLF) in zone of maximal involvement
