1 · What the graph read from it

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.

2 · The registry

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

BACKGROUND Worldwide, polycystic ovary syndrome (PCOS) is a prevalent endocrine and metabolic disorder that affects women of reproductive age. Naringenin is a natural flavanone, derived from grapefruit. The aims of this study were to investigate the effects of naringenin on the antioxidant and steroidogenic enzyme activity in a rat model of letrozole-induced PCOS. MATERIAL AND METHODS The induction of PCOS was undertaken by giving 28 female Sprague-Dawley rats a dose of letrozole (1 mg/kg) daily for 21 days. There were four treatment groups: Group I (n=7) received 1% of carboxymethyl cellulose (CMC); Group II (n=7) received 1% CMC plus naringenin 20 mg/kg; Group III (n=7) received letrozole only; Group IV (n=7) received letrozole plus naringenin 20 mg/kg. Estradiol, testosterone, and steroidogenic enzyme activities, superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) activity were determined in the four treatment groups, and histology was performed on the rat ovarian tissue. Serum glucose levels were measured with a glucometer. RESULTS Naringenin treatment in a rat model of PCOS significantly increased the levels of the reactive oxygen species (ROS) scavenging enzymes CAT, SOD, and GPX (p<0.05), and prevented weight increase. Naringenin treatment resulted in a significant reduction in serum glucose levels (p<0.05), normalized estradiol and testosterone levels steroidogenic enzyme activity, and maintained the normal anatomy of the ovaries. CONCLUSIONS Naringenin treatment, in a rat model of PCOS, demonstrated antioxidant and steroidogenic enzyme activity.
