Dichotomized combination variables of EPHB6/TrkA, EFNB2/TrkA, and EFNB3/TrkA strongly predict outcome of NB. Dichotomized variables were generated based on TrkA expression and EPHB6, EFNB2, or EFNB3 expression. One category included NB expressing low levels of both TrkA and EPHB6, EFNB2 or EPNB3, (group 1 in Fig. 2), whereas the other included NB expressing high levels of either one or both (combination of groups 2, 3, and 4 in Fig. 2). Survival probabilities of each two groups of NB defined by the dichotomized combination variables, EPHB6/TrkA (A), EFNB2/TrkA (B), and EFNB3/TrkA (C), were estimated by the method of Kaplan-Meier. The log-rank test was used to compare survival probabilities of the groups. CI, Confidence interval.
