According to the new data based on SMOTE (n = 240), the expression level of METTL1 in the IPF group was higher than that in the normal group (p < 0.05); in contrast, the expression of RNMT between the two groups was not statistically different (p = 0.42) (Figure 2A). This evidence concerns the gene METTL1 and idiopathic pulmonary fibrosis.
