Comparative developmental competence and gene expression in laparoscopically retrieved- and abattoir-derived goat oocytes.
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. An erratum has been issued. 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
Introduction: Advancing Materials and methods: We compared the developmental competence and gene expression in bakerwal goat oocytes obtained via LOPU and from abattoir-sourced ovaries. A total of 528 cumulus oocyte complexes (COCs) were collected from 12 live donors across three LOPU sessions, while 1,517 COCs were retrieved from 338 abattoir ovaries. All oocytes underwent Results: LOPU-derived oocytes demonstrated significantly higher developmental performance, including cleavage (54.9% vs. 45.2%), morula (45.9% vs. 34.9%), and blastocyst rates (29.5% vs. 19.0%; Conclusion: In goats, oocytes retrieved via LOPU show superior developmental competence and more favorable molecular signatures than those obtained from abattoir-derived ovaries. LOPU-derived oocytes provide a more reliable option for achieving higher -quality embryos and may be more suitable for application in advanced reproductive biotechnologies.
