The BIC-scores in the subgroups adenoLC (involved marker LC:AhR/Wnt = 6:–), SCLC (3:–) and smokers (7:–) contained LC-markers only, whereas AhR/Wnt-markers are included even under this stringent variable selection in the subgroups SqCLC (5:1) and Early onset LC (2:2). Here, AHR is linked to laryngotracheoesophageal cleft.
