The flow chart of participants and their follow-up is shown in Figure 1. A total of 44 cases completed the study. Four patients were excluded from the study because of personal reasons (three patient) and allergy to Nigella sativa oil (one patient). At baseline, there was no significant difference in general characteristics between the groups (Table 1). The results of our study showed that NS oil supplementation had no significant effect on serum levels of leptin and adiponectin (p >0.05). Also, no significant effect were seen with this supplementation on systolic and diastolic blood pressure among patients with NAFLD (Table 2).
