A novel threshold for determining NPD subtypes. A ASM levels in clinical cases are collected. B ROC curve for the predictability of the threshold. ASM ratio, the ratio of the activity of acid sphingomyelin phosphodiesterase of the patients to the reference value; NPA, Niemann–Pick disease type A; NPB, Niemann–Pick disease type B; ROC, receiver operating characteristic curve; AUC, area under the curve
