NOTE: Comparisons between groups were analyzed as described in the Methods. Groups: High=patients with higher expression of lnc-BMP1-1 in lung cancer tissues compared with their adjacent normal lung tissues; Low = patients with lower expression of lnc-BMP1-1 in lung cancer tissues compared with their adjacent normal lung tissues. a, Pearson χ2 test for high vs. low gene (lnc-BMP1-1 or Cav-I) expression groups combining clinical characteristics. Significance (bold values), p<0.05.
Abbreviations: N, number of subjects in each group; Lc history, lung cancer history.
