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
Although the effects of noise-induced hearing loss (NIHL) on cognitive functions have been widely investigated, the cognitive effects of noise-induced hidden hearing loss (NIHHL), particularly its impact on memory, remain poorly understood. The Dnah11 gene, which encodes a dynein motor protein involved in synaptic development, may play a role in NIHHL-related cognitive impairment. We aimed to investigate whether NIHHL induces memory impairment and explore the role of Dnah11 expression in this process. Behavioral experiments identified the peak of memory impairment at 1 month following noise exposure. To elucidate molecular changes, hippocampal gene expression was analyzed using transcriptomic sequencing, reverse transcription quantitative polymerase chain reaction (RT-qPCR), and immunofluorescence. RNA sequencing revealed significant Dnah11 upregulation, with immunofluorescence confirming DNAH11 overexpression in hyperactivated CaMKIIα-positive excitatory neurons. Stereotaxic injection of recombinant adeno-associated virus (rAAV) vectors to knock down hippocampal Dnah11 expression improved memory performance in NIHHL mice without improving hearing loss. This cognitive improvement was accompanied by partial restoration of synaptic plasticity-related proteins, including SYN and PSD95. These findings indicate that Dnah11 upregulation in hippocampal excitatory neurons contributes to NIHHL-induced memory impairment, and targeting Dnah11 may offer a therapeutic strategy for memory impairment associated with hidden hearing loss.
