Absence of hippocampal pathology persists in the Q175DN mouse model of Huntington's disease despite elevated HTT aggregation.

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
BackgroundHuntington's disease (HD) is a neurodegenerative disorder causing motor, cognitive, and psychiatric impairments, with the striatum being the most affected brain region. However, the role of other regions, such as the hippocampus, in HD remains less understood.ObjectiveHere, we study the comparative impact of enhanced mHTT aggregation and neuropathology in the striatum and hippocampus of two HD mouse models.MethodsWe utilized the zQ175 as a control HD mouse model and the Q175DN mice lacking the PGK-Neomycin cassette generated in house. We performed a comparative characterization of the neuropathology between zQ175 and Q175DN mice in the striatum and the hippocampus by assessing HTT aggregation, neuronal and glial pathology, chaperone expression, and synaptic density.ResultsWe showed that Q175DN mice presented enhanced mHTT aggregation in both striatum and hippocampus compared to zQ175. Striatal neurons showed a greater susceptibility to enhanced accumulation of mHTT in Q175DN. On the contrary, no signs of hippocampal pathology were found in zQ175 and absence of hippocampal pathology persisted in Q175DN mice despite higher levels of mHTT. In addition, Q175DN hippocampus presented increased synaptic density, decreased Iba1
