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
introductionAdults with Down syndrome demonstrate striatum-first amyloid accumulation with [
methodsLongitudinal PiB (n = 175 participants) and FBP (n = 92 participants) data from the Alzheimer Biomarkers Consortium-Down Syndrome (ABC-DS) were used to measure cortical and striatal binding. Generalized temporal models for cortical and striatal amyloid accumulation were created using the sampled iterative local approximation (SILA) method.
resultsPiB demonstrated greater striatal-to-cortical ratios than FBP. SILA analysis revealed striatal amyloid burden occurs 3.40 (2.39) years earlier than the cortex in PiB. There was no difference between the cortex and striatum in FBP. DISCUSSION: Among adults with Down syndrome, the striatum consistently accumulates amyloid earlier than the cortex when measured with PiB. This suggests the striatum is more sensitive to the onset of PiB PET-detectable amyloid in Down syndrome. HIGHLIGHTS: Striatal amyloid is detectable 3.4 years before the cortex using PiB PET in DS. Florbetapir PET does not detect early striatal amyloid accumulation in DS. White matter can be used as reference region in longitudinal florbetapir PET. SILA trajectory models can be used to compare regional estimates for age of onset.
