SECTM1 and non-small cell lung carcinoma: As shown in Figure 4D, survival analyses indicated that high expression of IGFBP7 and RFTN1 (green line) is associated with a superior prognosis in NSCLC patients (p < 0.05), while the expression of WFDC21P and SECTM1 is not associated with prognosis (p < 0.05) (Figure S2A, B).
