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

Drug resistance is an important cause of antiretroviral therapy failure in human immunodeficiency virus (HIV)-infected patients. Mutations in the protease render the virus resistant to protease inhibitors (PIs). Gag cleavage sites also mutate, sometimes correlating with resistance mutations in the protease, but their contribution to resistance has not been systematically analyzed. The present study examines mutations in Gag cleavage sites that associate with protease mutations and the impact of these associations on drug susceptibilities. Significant associations were observed between mutations in the nucleocapsid-p1 (NC-p1) and p1-p6 cleavage sites and various PI resistance-associated mutations in the protease. Several patterns were frequently observed, including mutations in the NC-p1 cleavage site in combination with I50L, V82A, and I84V within the protease and mutations within the p1-p6 cleavage site in combination with D30N, I50V, and I84V within the protease. For most patterns, viruses with mutations both in the protease and in either cleavage site were significantly less susceptible to specific PIs than viruses with mutations in the protease alone. Altered PI resistance in HIV-1 was found to be associated with the presence of Gag cleavage site mutations. These studies suggest that associated cleavage site mutations may contribute to PI susceptibility in highly specific ways depending on the particular combinations of mutations and inhibitors. Thus, cleavage site mutations should be considered when assessing the level of PI resistance.
