Phytic acid alleviates ochratoxin A-induced renal damage in chicks by modulating ferroptosis and the structure of the intestinal microbiota.

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
Phytic acid (PA) is a natural antioxidant with various biological activities, providing protective effects in multiple animals. Ochratoxin A (OTA) is a mold toxin commonly found in feed, which induces multi-organ damage, with kidney being the target organ of its toxicity. This study investigates the protective effects of PA on OTA-induced renal damage and its potential mechanisms in chicks. The results demonstrates that PA treatment restores OTA-induced renal pathological injuries, reverses the diminished activities of antioxidant enzymes, reduces the accumulation of malondialdehyde, and normalizes the expression of pro-inflammatory cytokines, which confirms that PA can alleviate OTA-induced renal damage. Further investigations reveal that OTA-induced renal injury accompanied by an increase in tissue iron content and the transcription levels of ferroptosis-related genes (TFR, ACSL4, and HO-1), and a decrease in the levels of SLC7A11 and GPX4. PA treatment reverses all these effects, indicating that PA mitigates OTA-induced renal ferroptosis. Moreover, PA supplementation improves intestinal morphology and mucosal function, corrects OTA-induced changes in the intestinal microbiota. Besides, PA microbiota transplantation alleviates renal inflammation and oxidative stress caused by OTA. In conclusion, PA plays a protective role against renal damage through the regulation of ferroptosis and the intestinal microbiota, possibly providing novel insights into the control and prevention of OTA-related nephrotoxicity.
