Microplastics in the seminal microenvironment of boar semen: associations with sperm motility and antimicrobial susceptibility.
Article in Frontiers in veterinary science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Microplastics (MPs) are increasingly recognized as environmental contaminants capable of interacting with biological systems. However, their presence in livestock reproductive fluids remains relatively unexplored. In swine artificial insemination, boar semen quality is a key determinant of reproductive efficiency, and spermatozoa are highly susceptible to physicochemical stressors present in their surrounding microenvironment. Particulate contaminants such as MPs may therefore represent an overlooked factor relevant to semen quality. The present study investigated the occurrence, polymer composition, and size distribution of MPs in undiluted boar semen using μFTIR spectroscopy. In addition, exploratory analyses were conducted to evaluate potential associations between MPs and semen motility parameters assessed using computer-assisted sperm analysis (CASA) system, as well as bacterial load and antimicrobial susceptibility profiles of bacteria isolates. MPs were detected in all analyzed semen samples (
