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
introductionHigh fructose intake has been implicated as a risk factor for behavioral disorders, potentially through cell ferroptosis induction in the central nervous system. Neural stem cells (NSCs) are crucial for maintaining hippocampal neurogenesis to resist behavioral alterations. Gastrodin, derived from the traditional Chinese herb Gastrodia elata, has neuroprotective effect.
objectivesThis study aimed to elucidate the underlying mechanism by which high fructose induces sweet taste preference and assesses the impact of gastrodin on hippocampal NSC ferroptosis.
methodsMice and cultured NSCs were treated with high fructose and/or gastrodin, respectively. NSC ferroptosis was evaluated by assay of lipid peroxidation and DNA double-strand breaks. Transcriptome sequencing (RNA-seq), Western blotting, and chromatin immunoprecipitation (ChIP) were employed to explore the potential mechanism underlying high fructose-induced NSC ferroptosis and the modulation of gastrodin. Simultaneously, specific gene expression was regulated by lentivirus injection into the hippocampus of mice.
resultsOur data showed that gastrodin mitigated sweet taste preference decline and hippocampal NSC ferroptosis in high fructose-fed mice, being consistent with reduction of reactive oxygen species (ROS) and iron accumulation in hippocampal NSC mitochondria. Mechanistically, we identified CDGSH iron-sulfur domain 1 (CISD1) as a mediator of NSC ferroptosis, with its expression being augmented by high fructose. Overexpression of Zic family member 2 (ZIC2) increased the transcription of Cisd1 gene. Additionally, overexpression of Zic2 with lentiviral vectors in hippocampus showed the decreased sweet taste preference in mice, consistently up-regulated CISD1 protein expression and reduced hippocampal NSC number. Gastrodin downregulated ZIC2 expression to inhibit CISD1 transcription in its attenuation of high fructose-induced NSC ferroptosis and sweet taste preference decrease.
conclusionCollectively, high fructose can drive hippocampal NSC ferroptosis by upregulating ZIC2 and CISD1 expression, thereby contributing to the decline in sweet taste preference. Gastrodin emerges as a promising agent for mitigating NSC ferroptosis and improving sweet taste preference.
