Kaplan-Meier five year survival curve for TNFα densities in the tumour islets for each tumour stage using upper and lower tertile values for TNFα density. For comparison of upper tertile stage I versus lower tertile stage I p = 0.06, for upper tertile stage II versus lower tertile stage II p = 0.18, for upper tertile stage IIIa versus lower tertile stage IIIa p = 0.55, and for upper tertile stage IIIa versus lower tertile stage I p = 0.70.
