Figure 2.

KLK6 mRNA levels in lymph nodes of stage I to IV CRC patients and control patients (Ctr). Each of the 166 CRC patients and 23 control patients is represented by the lymph node with the highest KLK6 level. (A) All patients, (B) patients with at least one H&E(+) lymph node available for mRNA analysis (C) patients with only H&E(−) lymph nodes available for mRNA analysis. Filled circles represent patients who have died in CRC or are living with recurrent disease. Open circles represent living, disease-free patients and patients who have died from other causes than CRC. For clarity dots indicating KLK6(−) patients who have died from CRC are positioned slightly above those who are alive in (B) and (C).
