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
Oxytetracycline (OTC) is one of the few antibiotics approved by the U.S. Food and Drug Administration for catfish aquaculture. Unfortunately, OTC resistance has been frequently detected in production environments, with the fish gut identified as a potential hotspot for resistance selection. In aquaculture systems, water temperature is a critical factor influencing fish physiology, antibiotic pharmacokinetics, and water resistome development. However, its role in modulating OTC effects on the fish gut microbiome remains underexplored. This study examined temperature-dependent microbiome and resistome responses in channel catfish ( IMPORTANCE: This study reveals that water temperature critically shapes how antibiotics affect the gut microbiome and antimicrobial resistance in channel catfish. Metagenomic sequencing results showed that oxytetracycline (OTC) treatment caused minimal disruption of the microbiome at 20°C, but induced significant community shifts and enrichment of antimicrobial resistance genes (ARGs) at 25°C and 30°C. Higher temperatures reduced microbial resilience, consolidating ARGs within key bacterial genera such as
