Fetal-to-fetal kidney transplantation in utero.
Article in Communications biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Potter sequence consists of various symptoms associated with renal dysplasia. For bilateral renal agenesis, there is no hope of survival. As a novel therapeutic approach for Potter sequence, we develop a unique approach of "transplantation of fetal kidneys from a different species during the fetal stage." In this study, we first validate the approach using allogeneic transplantation. Fetal kidneys with bladders from green fluorescent protein-expressing rats (embryonic day 14.0-16.5) are subcutaneously transplanted into allogeneic rat fetuses in utero (embryonic day 18.0-18.5). After birth, the transplanted fetal kidneys are confirmed to have urine production capability. Furthermore, long-term (up to 150 days) urine production is sustained. Next, we perform xenotransplantation. The transplantation of mouse fetal kidneys into rat fetuses in utero leads to the maturation of renal tissue structures. We demonstrate organ transplantation into in utero fetuses using fetal kidneys as donor organs for fetal therapy.
