From HIV to SARS-CoV-2 associated neurological disorder ("HAND" to "SAND"): Viral infection as a "time-bomb" for the aging brain.
Review in Neuroscience applied, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
In 2020, a novel Coronavirus, Severe Acute Respiratory Syndrome-Covid-2 (SARS-CoV-2), spread globally to provoke a pandemic that infected over 750 million people. The associated disorder, Coronavirus-19 (COVID-19), has caused at least 7 million deaths and around a hundred million people have developed a variable yet sometimes incapacitating condition called Long Covid. This multi-organ syndrome, often referred to as "Brain Fog", encompasses symptoms of extreme fatigue, anxiety, poor sleep and, most prominently, cognitive impairment. Long Covid emerges three or more months after SARS-CoV-2 infection and bears a marked resemblance to the suite of neurological symptoms that evolves several years after infection with Human Immunodeficiency Virus (HIV). Accordingly, by analogy to "HIV Associated Neurological Disorder" (HAND), the acronym," SAND" is proposed for SARS-CoV-2 Associated Neurological Disorder. Mimicking HIV infection/HAND, SARS-CoV-2 infection/SAND is on a collision course with aging, leading to their mutual aggravation and an increased risk of disorders like Alzheimer's and Parkinson's disease. In contrast to HIV, where the virus crosses the blood-brain-barrier in T-lymphocytes and monocytes to infect microglia and other cell types, there is
