Expression of ID2 in NSCLC Figure 2. Graphic representation of multiple correspondence analysis (A) and DEMOD analysis results (B). A: Nuclear, cytoplasmic, and global expression of ID2 within NSCLC tumors have been used as active variables and are represented by bold squares and circle. Clinicopathological features (i.e., differentiation, histological type, genre, smoking status, stage, and TNM classification) have been used as illustrative variables and are represented by open lozenge. All variables were placed according to the gravity center of all patients belonging to the represented category. Clinical parameters potentially associated with ID2 expression are underlined and in italics. B: DEMOD analysis was performed to identify statistical associations between ID2 expression and clinicopathological features. Only parameters identified with MCA have been presented in the table (i.e., histological type, T status, lymph node involvement status, and differentiation of tumor). doi:10.1371/journal.pone.0004158.g002 PLoS ONE | www.plosone.org 4 January 2009 | Volume 4 | Issue 1 | e4158
