Table 2.
Frequency and degree of anaemia for different cancer sites. All Hb figures represent g/L. Colonic cancer was more likely to be anaemic with lower Hb compared with rectal cancers (p < 0.001). As would be expected, right-sided cancers had the lowest Hb although with relatively small absolute differences (p < 0.001)
