The nsP3 macro domain is important for Sindbis virus replication in neurons and neurovirulence in mice.

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
Sindbis virus (SINV), the prototype alphavirus, contains a macro domain in the highly conserved N-terminal region of nonstructural protein 3 (nsP3). However, the biological role of the macro domain is unclear. Mutations of amino acids 10 and 24 from asparagine to alanine in the ADP-ribose binding region of the macro domain impaired SINV replication and viral RNA synthesis particularly in neurons, but did not alter binding of poly(ADP-ribose). Mutation at position 10 had the greatest effect and caused nsP3 instability in neurons, decreased SINV-induced death of mature, but not immature neurons, and attenuated virulence in 2 week-old, but not 5 day-old mice. A compensatory mutation at amino acid 31 in the macro domain of nsP3, as well as reversion of mutated amino acid 10, occurred during replication of double mutant SINV in vitro and in vivo. The nsP3 macro domain is important for SINV replication and age-dependent susceptibility to encephalomyelitis.
