Table 3. Comparisons of DAT and DRD2 mRNA levels between the three groups (Mean±SD).

	Acute patients	Chronic patients	Controls	F	P-value
	(N = 25)	(N = 27)	(N = 30)
DAT	0.48±0.24	0.58±0.21▴	0.39±0.24	4.330	0.017*
DRD2	0.32±0.13	0.37±0.19	0.34±0.09	0.510	0.605

In the homogeneity test of variance, the Levene value of DAT mRNA levels in the three groups was 0.37 (p = 0.692), and the One-way ANOVA and LSD methods were chosen; the Levene value of DRD2 mRNA levels in the three groups was 4.89 (p = 0.011), and the Welch approximate analysis of variance and Tamhane methods were chosen.
