The effect of evening primrose oil on adolescent girl patients with PCOS: A double-blind placebo-controlled randomized study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: Polycystic ovary syndrome (PCOS) is a common disorder among women of reproductive age. The goal of the current study was to evaluate the effect of evening primrose oil (EPO) (Oenothera biennis) in adolescent girls with PCOS. Materials and Methods: In the current double-blind and randomized controlled research, 76 patients completed the study in two groups (38 in the placebo and 38 in the EPO groups). The patients were asked to take oral placebo or EPO (1000 mg/day) for 12 weeks. Biochemical, clinical, and ultrasonography assessments were performed. The data was analyzed using SPSS statistical software. Results: After the intervention, the regulation of the menstrual cycle in the EPO group was different from that of the placebo group (p=0.04). The levels of insulin, testosterone, and free androgen index (FAI) in the EPO group were lower than those of the placebo group (p<0.05). The sex hormone binding globulin (SHBG) levels in the EPO group were higher than those of the placebo group (p=0.01). While the number of immature follicles decreased in the EPO group, this difference was not statistically significant (p=0.8). Conclusion: Overall, EPO administration for 12 weeks in young women with PCOS regulated the irregular menstrual cycle. In addition, the levels of insulin, testosterone, FAI, and SHBG changed. Therefore, EPO may be effective in improving hormonal and menstrual irregularities.
