Arteriolosclerosis in CNS Tissues Outside the Cerebrum and Late-Life Motor Impairment.

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
backgroundThe pathological basis underlying motor impairment in older adults is partially accounted for by Alzheimer disease and related dementias pathologies. We tested the hypothesis that arteriolosclerosis, a pathological correlate of small vessel disease, outside the cerebrum is related to motor impairment in older adults above and beyond Alzheimer disease and related dementias pathologies.
methodsThe data were from decedents of a community-based clinical-autopsy study. Arteriolosclerosis was assessed in the cerebrum (as 1 of 10 Alzheimer disease and related dementias pathologies), midbrain, cerebellum, pons, and 4 levels of the spinal cord. Parkinsonism was assessed using the Unified Parkinson Disease Rating Scale. Other motor performances included timed-peg placement and finger tapping, grip and pinch strength, walking 8 ft and turning 360° twice, and sensor-derived metrics assessing tandem walk. Multivariate linear regression models were used to examine the association of arteriolosclerosis across varied motor performances.
resultsThe participants (n=403) were on average 91.4 (6.1) years old at death, and 73.2% (n=295) were women. The frequency of moderate/severe arteriolosclerosis varied outside the cerebrum, ranging from 15.5% (40/258) in the pons to 49.6% (200/403) in the spinal cord. The correlation of the severity of arteriolosclerosis between these regions ranged from unrelated to modestly related. Spinal arteriolosclerosis was associated with impaired motor function (
conclusionsArteriolosclerosis severity varies in the central nervous system tissues outside of the cerebrum and is differentially associated with varied motor performances, suggesting that the adverse motor consequences of small vessel disease in older adults may be underestimated by studies focusing only on the brain.
