Liver Injury Indicating Fatty Liver but Not Serologic NASH Marker Improves under Metformin Treatment in Polycystic Ovary Syndrome
Table 2
Outcome parameters at baseline and after 6-month metformin treatment for patients with PCOS who were insulin sensitive at baseline (PCOS-C), patients with IR at baseline and after treatment (PCOS-PIR), and initially insulin resistant patients whose IR dissolved after treatment (PCOS-exIR).

Data were analyzed with repeated measures analysis of variance with the factors group (i.e., PCOS-C, PCOS-IR, and PCOS-exIR) and time (i.e., changes from baseline to 6 months of treatment). In case of significant ANOVA time or time × group effects, post hoc paired -tests within respective PCOS groups were calculated (, and nonsignificant after Bonferroni correction). Changes in BARD-Scores from baseline to 6 months after treatment were analyzed with Wilcoxon tests within subgroups and the total sample. All results are shown as mean ± standard deviation, unless otherwise indicated.
