Fig 8. Correlations between the relative mRNA expression of various components of the S1P signalling system and lung function (fev1).
Significant (p<0.05) correlations were found between fev1 and (A) SPHK1 (B) S1PR1 (C) S1PR3, (D) S1PR5, p<0.05. The correlation coefficients are listed in the results.
