doi: 10.3390/jpm13030496

Figure Lengend Snippet: Figure 3. Correlation of the clinicopathological parameters with PFS in CRC patients with liver oligometastases. Survival curves were generated using the Kaplan–Meier method, and differences between survival curves were estimated using the log-rank test. (a) We divided all patients into four groups based on IDO1 and COX2 expression levels. Group I: IDO1LowCOXLow; Group II: IDO1HighCOXLow; Group III: IDO1LowCOXHigh; Group IV: IDO1HighCOXHigh. The association of the four groups (IV vs. I/II/III) with PFS was significant (p = 0.0024); (b,c) correlation between CEA and N stage and PFS in patients; c: N stage (p = 0.026); b: CEA (p = 0.006). (d–n): Correlation between other clinicopathological parameters and PFS in patients. (p > 0.05).
