1 · What the graph read from it

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.

2 · The registry

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

backgroundIndole-3-acetic acid (IAA)-based hydrazone derivatives, exemplified by specifically (E)-2-(1H-indol-3-yl)-N'-(3-methoxybenzylidene) acetohydrazide acetohydrazide (MBIH) and (E)-N'-(4-fluorobenzylidene)-2-(1H-indol-3-yl) acetohydrazide (FBIH), have garnered significant attention in the field of heavy metal toxicity for their potent antioxidant and cytoprotective properties.

methodsThis study evaluated their efficacy, alongside ascorbic acid (AA), in mitigating sub-chronic cadmium (Cd) toxicity in a rat model. Sixty Swiss albino rats were randomized into five groups: control, Cd-exposed, Cd + AA (100 mg/kg), Cd + MBIH (10 mg/kg), and Cd + FBIH (10 mg/kg). Following 28 days of treatment, we assessed body weight trajectories, fasting blood glucose, and HbA1c. Serum biomarkers of hepatic, renal, inflammatory, and lipid function were quantified. Antioxidant capacity was measured via glutathione (GSH) assays and qRT-PCR analysis of SOD2, CAT, Nrf2, and Hmox 1 expression. Untargeted LC-MS/MS metabolomic profiling of serum identified disturbances in amino acids and lipid species, while histopathology of brain, liver, and pancreas documented structural injury.

resultsCd exposure induced significant weight loss, hyperglycemia, and elevated HbA1c, alongside dyslipidemia and heightened inflammatory markers. Hepatic and renal dysfunction, GSH depletion, and downregulation of antioxidant genes confirmed oxidative stress. Metabolomics revealed a Cd-specific fingerprint characterized by altered sulfur amino acid and phospholipid metabolism. Histologically, Cd caused liquefactive necrosis in the brain, inflammatory infiltrates in the liver, and acinar cell vacuolization with islet distortion in the pancreas. In contrast, MBIH and FBIH restored glycemic control, lipid profiles, inflammatory and hepatic renal markers, replenished GSH, and upregulated antioxidant genes via robust Nrf2 activation.

conclusionsThese findings demonstrate that IAA-based hydrazone derivatives MBIH and FBIH afford superior protection against Cd-induced multi organ injury compared to ascorbic acid.
