AKR1C2 and schizophrenia: Of the 26 molar ratios that may reflect a balance between AKR1C2 on one side and HSD17B2 and HSD17B6 on the other, 7 are lower, 13 are not significantly different, and 6 are higher in patients compared with controls (p = 0.792, Mann–Whitney test), suggesting the absence of a significant trend in relation to schizophrenia.
