SERPINH1 and lung cancer: Logistic regression analysis identified age (OR 1.055, 95% CI 1.007–1.109, p = 0.028), male sex (OR 22.50, 95% CI 4.535–408.2, p < 0.001), history of smoking (OR 11.70, 95% CI 3.243–75.17, p < 0.001), and a high number of HSP47-positive fibroblasts (OR 4.627, 95% CI 1.990–11.23, p < 0.001) to be significant risk factors for death because of lung cancer after surgery.
