1 · What the graph read from it

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.

2 · The registry

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

Murid herpesvirus 4 (MuHV-4) currently serves as a model for study of human gamma-herpesvirus pathogenesis. It codes for MK3 protein that similarly as K5 protein of Kaposi's sarcoma-associated herpesvirus are members of a family of structurally related viral immune evasion molecules possessing RING-CH finger domain with ubiquitin ligase activity. Murine herpesvirus 72 (MHV-72) isolated from the same species of free-living small rodent is considered as closely related to Murine herpesvirus 68 (MHV-68). Studies on MHV-72, identified dissimilarity from MHV-68 in the sequence of glycoprotein 150 [K. Macáková, J. Matis, I. Rezuchová, O. Kúdela, H. Raslová, M. Kúdelová, Virus Genes 26, 89-95 (2003)]. Murine herpesvirus 4556 (MHV-4556) is relatively new, till now, uncharacterised strain isolated from different murid species Apodemus flavicollis. We have therefore sequenced the MK3 gene of MHW-72 as well as of MHV-4556 to find out the evidence of their difference from that of MHV-68. We show here the unique nucleotide mutation in MHV-72 MK3 gene changing the codon at C-end of MK3 protein that was earlier predicted to function in interaction with TAP1/2. Furthermore, one from two nucleotide mutations found for MHV-4556 MK3 gene changed the codon that is localized at N-terminus of MK3 protein. MHV-4556-specific mutation was found within MK3 RING-CH finger domain known to be necessary for the ubiquitination of MHC class I proteins. Moreover, the latter established the new restriction site specific for MHV-4556.
