Median MBL plasma levels were markedly elevated in the IPF and sarcoidosis group when compared to the control group, although the difference was not statistically significant (Table 2 and Figure 1, IPF, median 1511 ng/ml, p = 0.44; Sarcoidosis 1111 ng/ml, p = 0.11; Control 879 ng/ml). Here, MBL2 is linked to sarcoidosis.
