Development of a convenient and rapid screening zebrafish model to investigate lethal effects and immunocompromised states of uremic toxins.
Article in Renal failure, 2025. 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
backgroundUremia is characterized by high mortality and immune dysfunction owing to the accumulation of uremic toxins. Traditional rodent models are complex and time consuming. This study aimed to develop a simple and rapid zebrafish model for investigating the toxicological effects of uremic toxins.
methodsUremic solutions containing small (SUT) and medium-to-large (MLUT) uremic toxins were prepared using waste solution of peritoneal dialysis by a dialysis method. Wild-type zebrafish larvae were used to assess mortality, whereas transgenic (TG) (zlyz:EGFP) zebrafish, with macrophages labeled with green fluorescent protein, were used to evaluate immune status through macrophage migration assays.
resultsThe mortality rates were significantly higher in the SUT- and MLUT-treated groups than in the controls, with SUT showing the strongest lethal effect. Macrophage migration was significantly inhibited in both SUT- and MLUT-treated groups, indicating an immunocompromise. This model effectively mimicked the lethal and immunosuppressive effects of uremia.
conclusionThis zebrafish model provides a simple and rapid platform for studying the toxicological effects of uremic toxins and evaluating potential therapeutic interventions.
