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
The molecular mechanism underlying male reproductive toxicity associated with Perfluorooctanoic acid (PFOA), a persistent environmental endocrine disruptor (EDC), has not yet been fully elucidated. Six-week-old male C57BL/6 mice were treated with PFOA by oral gavage at 0, 1.25, 5, 10, and 20 mg/kg/day for 35 days to explore its toxic effects on the male reproductive system and the underlying mechanisms. Analyses of semen quality, testicular histopathology, and blood-testis barrier (BTB) integrity revealed that PFOA caused dose-dependent structural and functional damage to the BTB, leading to markedly reduced semen quality. Based on transcriptomic sequencing and differential gene enrichment analysis, the glycolytic pathway was identified as a key regulatory target for PFOA-induced damage to the reproductive system. Further validation revealed that PFOA exposure inhibited glycolysis-related enzymes (Hexokinase 1 (HK1), Glucose Transporter 1 (GLUT1), and Lactate Dehydrogenase A (LDHA)), reduced lactate production and ATP synthesis, lowered Pan-Kla and H3K18la levels, and diminished H3K18la enrichment at the
