Relationship between orthostatic hypotension, internal carotid artery blood flow, and cognition in patients with cervical spinal cord injury.

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
Introduction: This study aimed to identify the distribution of orthostatic hypotension (OH) according to changes in internal carotid artery (ICA) blood flow in patients with cervical spinal cord injury (SCI), and to determine whether cognitive impairment is more prominent among patients with a certain level of ICA blood flow reduction. Methods: Forty-one patients diagnosed with cervical SCI were retrospectively analyzed and classified into two groups based on the results of a head-up tilt test and carotid duplex ultrasonography to measure ICA blood flow: those with a reduction of 21% or more ( Results: Patients with an ICA blood flow reduction of 21% or greater demonstrated significantly lower cognitive scores than those without such a reduction (K-MMSE Discussion: This study suggests that the early assessment of ICA blood flow and cognitive function may be informative in the rehabilitation process for patients with cervical SCI. Whether such assessment can help identify patients who should be prioritized for formal cognitive assessment requires prospective evaluation.
