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
Alzheimer's disease (AD) pathology has been recently shown to accumulate in multiple brainstem nuclei in pre-cortical disease stages. However, the impact of neurotransmission alterations on brain atrophy and their genetic correlates in AD remain unexplored. This study investigated (1) associations between grey matter (GM) loss and uptake values of PET/SPECT ligands tracing concentration of multiple neurotransmitter receptors/transporters and pathways; (2) the impact of AD polygenic risk scores (AD-PRSs) on such associations along the AD continuum. T1-weighted MRI scans, genetic and clinical data were selected for 800 ADNI participants: 203 cognitively unimpaired older adults (CU), 442 with mild cognitive impairment (MCI) and 155 with AD. JuSpace was used to calculate correlations between GM volume (GMV) and the concentration of several neurotransmitters. Two PRSs, with (AD-PRS) and without APOE (AD-PRS
