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

Chlorpyrifos (CPF) is a commonly used organophosphorus insecticide in agriculture, and it is linked to reproductive toxicity in males by disrupting the endocrine system. Most previous studies focus on its traditional form, neglecting its nanoform, which may pose a greater risk due to enhanced bioavailability. Our study evaluated the reproductive toxicity of a nano-emulsion of CPF (CPF-NE) in male albino mice. Mice were divided into four groups (n = 10 per group): a control and three treated groups receiving CPF-NE via oral gavage at doses of 3.79, 7.58, and 15.16 mg/kg body weight daily for 35 days. We assessed gonadosomatic index (GSI), reproductive performance (mating success and fertility rate), sperm parameters, DNA fragmentation, hormonal levels (testosterone, FSH, LH), total antioxidant capacity (TAC), malondialdehyde (MDA), and catalase (CAT). Post-treatment testes were examined histologically. Results showed that CPF-NE significantly decreased GSI (from 0.66 ± 0.02 in controls to 0.31 ± 0.02 in high-dose, p < 0.001), reproductive performance (fertility index dropped to zero at high dose), sperm viability (from 74 ± 1.6% to 43.1 ± 1.7%, p < 0.001), and testosterone (from 4.2 ± 0.3 ng/mL to 1.8 ± 0.2 ng/mL, p < 0.001), while increasing FSH, LH, MDA, and DNA fragmentation. Histopathological findings indicated reduced tubular diameters, decreased epithelial heights, and disrupted testicular structure. In conclusion, CPF-NE adversely affects male fertility by increasing oxidative stress and DNA damage.
