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

Previous studies demonstrated that the nef gene is a critical determinant of the pathogenicity of simian immunodeficiency virus (SIV) in macaques. In the present study, we evaluated the effect of a spontaneous frameshift mutation in the C-terminus of the nef gene of the minimally pathogenic SIVsmH4i clone. This clone exhibited a single nucleotide deletion in the nef gene relative to pathogenic SIV clones that resulted in a frameshift and addition of 46 amino acids to the C-terminus of Nef. We generated a corrected version of this clone, SIVsmH4i Nef+ that restored Nef protein expression. Inoculation of macaques with SIVsmH4i resulted in delayed and low levels of peak viremia. This contrasted with improved kinetics and robust peak viremia in macaques inoculated with the corrected version. Despite the restoration of in vivo replication ability, neither clone resulted in memory CD4+ T cell loss or disease in a period of two years.
