The results of Fisher’s exact tests in arrayed patients/lesions with 5–7 histology grade; p = 0.20 in current vs. former smokers with SCA detection compared to no SCA detection, and p = 0.048 in persistence vs. regression of lesions with SCA detection compared to no SCA detection. Disease stability: persistent change; ≤ 1 histology grade, regressive change; ≥ 2 grades, -; no repeated bronchoscopy available.
