Porcine Corneal Tissue and Xenozoonotic Risks: A Review of the Current Evidence.
Review in Xenotransplantation. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Corneal opacities affect millions worldwide, with corneal transplantation as the primary treatment. However, donor shortages remain a challenge, leaving thousands waiting for transplants. Xenotransplantation using porcine corneas has emerged as a promising alternative due to anatomical and physiological similarities with human corneas. Advances in CRISPR/Cas technology enable genetic modifications to address immune rejection and zoonotic risks. A key concern is xenozoonosis, the transmission of infectious agents from pigs to humans. Pathogens such as porcine endogenous retroviruses (PERVs), porcine cytomegalovirus (PCMV), and bacteria pose potential risks. While PERVs can infect human cells in vitro, no transmission has been documented in vivo. Regulatory bodies, including the WHO and IXA, have established guidelines for monitoring and clinical trials. The first human corneal xenotransplantation trials in South Korea and China are underway. Enhanced biosecurity measures in tissue banks have reduced microbial contamination, improving safety. Corneal xenotransplantation presents lower risks compared to solid organ xenotransplants. With ongoing research, stringent regulations, and improved pathogen-free animal models, this technique could become a viable clinical option. Future human trials will provide crucial insights into its long-term safety and effectiveness.
