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
objectiveTo investigate mechanism of di-(2-ethylhcxyl)phthalate (DEHP) exposure in causing blood-testis barrier (BTB) impairment in rats.
methodsTwo-months-old male SD rats were randomly divided into corn oil control group and DEHP (750 mg/kg) exposure group for daily intragastic treatment for 30 consecutive days. After the treatments the rats were examined for histomorphological changes of the testicle using HE staining and the expressions of the junction proteins N-cadherin β-catenin, occludin and connexin43 of the BTB using Western blot. In the in vitro study, the vitality and ROS generation level in Sertoli cells exposed to different concentrations of DEHP were examined with MTT and ROS assay kits, respectively, and Nrf2 and p-p38 expressions were detected with Western blot.
resultsCompared with the control group, the rats with DEHP exposure showed structural damage of the seminiferous tubule and polarity loss of the spermatids. DEHP exposure caused significantly decreased expressions of occludin and connexin43 but increased expressions of N-cadherin and β-catenin in the testicle tissues of the rats (P<0.05). The vitality of Sertoli cells was obviously decreased and ROS level increased significantly after exposure of the cells to increasing concentrations of DEHP, which also resulted in significantly up-regulated Nrf2 and p-p38 expressions (P<0.05).
conclusionsDEHP exposure causes increased oxidative stress in the Sertoli cells of the testis, activates p38 MAPK signaling pathway, and results eventually in impaired spermatogenesis in rats.
