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
Background: Paclitaxel (PTX) chemotherapy frequently induces cognitive impairment, which is closely associated with two key pathological processes: necroptosis of hippocampal neurons and microglial polarization. Necroptotic neurons release damage-associated molecular patterns, triggering inflammatory responses. As the primary immune cells in the central nervous system, microglia can exhibit either pro-inflammatory or anti-inflammatory activity depending on their polarization state. However, the relationship between PTX-induced neuronal necroptosis and microglial activation remains unclear. Methods: In this study, both Results: The results demonstrated that PTX-induced necroptosis of hippocampal neurons activated microglia. Nec-1 effectively suppressed neuronal necroptosis and reduced M1 polarization of microglia. The TLR4/MyD88 signaling pathway was involved in microglial polarization induced by the necroptotic-conditioned medium of PTX-treated HT22 cells. TAK-242 significantly blocked the regulatory effect of PTX-induced neuronal necroptosis on BV-2 microglial polarization. Conclusion: This study reveals that hippocampal neuron necroptosis activates microglia through the TLR4/MyD88 signaling pathway in PTX-induced cognitive impairment, promoting M1 polarization and neuroinflammation. Inhibiting necroptosis promotes M2 polarization and neuroprotection. These findings uncover a novel mechanism of PTX-induced cognitive impairment and suggest potential therapeutic targets.
