TGFB3 and idiopathic pulmonary fibrosis: We also found a correlation between TGFB3 expression and the radiological pattern on HRCT, showing elevated TGFB3 expression with the presence of a UIP pattern, a probably UIP or an indeterminate for UIP compared with a NINE or a non-UIP pattern (0.0069 ± 0.0177 vs. 0.0010 ± 0.0007, p = 0.021, Table 2).
