Levels of ER stress proteins correlate with poor clinical outcome. Scatter plots of tumour/normal ratios of the ER stress proteins calreticulin (a), calnexin (b), GRP78 (c) and GRP94 (d) in the total CRC patient cohort with good versus poor outcomes. The tumour/normal ratio of calnexin was significantly increased in those patients had a poor clinical outcome compared with patients with good clinical outcome (**p < 0.01; Mann–Whitney U Test). The mean, median and STD were stated below the panels
