Fig. 3: Kaplan–Meier survival probability curve for the mucolipidosis types II and III (MLII and MLIII) phenotype.
From: Mucolipidosis type II and type III: a systematic review of 843 published cases

(a) Kaplan–Meier curve for the comparison of the survival probability of the MLII (gray) and MLIII (black) phenotype (log-rank test: P < 0.001). (b) Kaplan–Meier survival probability curve for the MLII and MLIII phenotype (log-rank test: P < 0.001) over three different time periods: <1980, 1981–2000, and 2001–2020.
