Virus persistence in an animal model of multiple sclerosis requires virion attachment to sialic acid coreceptors.
Article in Journal of virology, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Persistent Theiler's virus infection in the central nervous system (CNS) of mice provides a highly relevant animal model for multiple sclerosis. The low-neurovirulence DA strain uses sialic acid as a coreceptor for cell binding before establishing infection. During adaptation of DA virus to growth in sialic acid-deficient cells, three amino acid substitutions (G1100D, T1081I, and T3182A) in the capsid arose, and the virus no longer used sialic acid as a coreceptor. The adapted virus retained acute CNS virulence, but its persistence in the CNS, white matter inflammation, and demyelination were largely abrogated. Infection of murine macrophage but not oligodendrocyte cultures with the adapted virus was also significantly reduced. Substitution of G1100D in an infectious DA virus cDNA clone demonstrated a major role for this mutation in loss of sialic acid binding and CNS persistence. These data indicate a direct role for sialic acid binding in Theiler's murine encephalomyelitis virus persistence and chronic demyelinating disease.
