The initial statistical analysis revealed no correlation between MrgD expression at the tumor center or front and the patients’ age (tumor center: Spearman rho, r = 0.099, p = 0.361; tumor front: r = 0.145, p = 0.219) or gender (tumor center: chi-s, p = 0.679; tumor front, p = 0.568). The gene discussed is MRGPRD; the disease is neoplasm.
