CPT1-associated indicators were significantly changed especially in early Parkinson’s disease stages. (A,B) AC(16:0)/FA(16:0) ratios of Parkinson’s disease were significantly decreased in both cohorts. *P < 0.05; ***P < 0.001 (Wilcoxon’s test). (C,D) Multiple comparisons for the ratios, AC(16:0)/FA(16:0) and carnitine/AC(16:0). The decrease of AC(16:0)/FA(16:0) ratios were mainly detected in the early stage of Parkinson's disease. *P < 0.05; ***P < 0.001 (Steel’s test). (E,F) Carnitine/AC(16:0) ratios were increased significantly in the 1st cohort, but not significantly in the 2nd cohort. (G,H) Carnitine/AC(16:0) ratios were significantly increased in H&Y stage I. *P < 0.05; ***P < 0.001 (Wilcoxon’s test). (I,J) Ratios of AC(8:0)/AC(16:0) and AC(14:1)/AC(16:0) in each H&Y stage. Similar increase of AC(8:0)/AC(16:0) ratio in H&Y stage I was detected, however, this was not significant in the 2nd cohort. *P < 0.05; ***P < 0.001 (Steel’s test).
