Correlation with clinical parameters No significant associations were observed between serum VEGF-D levels and clinical parameters; however, serum VEGF-D showed a trend toward a weak correlation with DLCO ( r = −0.292, p = 0.072), and resting ( r = −0.397, p = 0.083) and lowest SpO 2 during the 6MWT ( r = −0.394, p = 0.086; Figure 3 and Supplemental Table S3 ).
