To evaluate the impact of SLIT2 levels on clinical and laboratory characteristics, we dichotomized our APL patients from the International Consortium of Acute Promyelocytic Leukemia (IC-APL) cohort [12] (IC-APL, n = 94) into low and high SLIT2 expression using the first quartile (p25) value. Here, SLIT2 is linked to acute promyelocytic leukemia.
