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

The HIV-1 matrix (MA) protein is similar to nucleocapsid (NC) proteins in its propensity for self-interaction and association with RNA. Here we report on our finding that replacing MA with NC results in the production of wild type (wt)-level RNA and virus-like particles (VLPs). In contrast, constructs containing MA as a substitute for NC are markedly defective in VLP production and form virions with lower densities than wt, even though their RNA content is over 50% that of wt level. We also noted that a DeltaMN mutant lacking both MA and NC produces a relatively higher amount of VLPs than those in which MA was substituted for NC. Although DeltaMN contains approximately 30% the RNA of wt, it still exhibits virion densities equal (or very similar) to those of wt. The data suggest that neither NC nor RNA are major virion density determinants. Furthermore, we noted that NC(ZIP)--a NC replacement with a leucine zipper dimerization motif--produces VLPs as efficiently as wt. However, the markedly reduced assembly efficiency of NC(ZIP) is associated with the formation of VLPs with densities slightly lower than those of wt following MA removal, suggesting that (a) MA is required to help the inserted leucine zipper motif perform efficient Gag multimerization, and (b) MA plays a role in the virus assembly process.
