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

Circadian rhythm disruption (CRD) is highly prevalent in modern society and contributes to numerous disorders, including erectile dysfunction (ED). Melatonin (MT) possesses well‑established functions in regulating circadian rhythm and demonstrating antioxidant ability; however, whether MT could preserve CRD‑induced ED and the underlying mechanism has never been reported. A rat model with CRD‑induced ED was designed by changing light‑dark cycle (2h:2h alteration) and then intraperitoneally administering MT with low (5 mg/kg/day) and high (10 mg/kg/day) dosages. A total of 4 weeks later, rats' erectile function was measured and penile corpus cavernosum was subsequently harvested for analysis. In addition, bioinformatics analysis was performed to filter the possible molecular target, while lipopolysaccharide (LPS)‑treated human umbilical vein endothelial cells (HUVECs) were selected to imitate CRD stimulation in vivo to further verify the underlying molecular mechanism. CRD significantly reduced rats' maximal intracavernous pressure (mICP) and mICP/mean arterial pressure (MAP) ratio, it also inhibited endothelial nitric oxide synthase/nitric oxide/cyclic guanosine monophosphate concentrations and injured normal penile corpus cavernosum structure, suggesting rats' normal erectile function was impaired; however, this CRD‑induced ED was preserved by MT.
