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 evolution of human immunodeficiency virus (HIV) type 1 nef quasispecies in a patient clonally infected with a contaminated batch of blood clotting factor IX was monitored. nef sequences were derived at 11, 25, and 41 months postinfection from infected peripheral blood mononuclear cells after molecular cloning of PCR-amplified proviral DNA. The phylogenetic relationships among a total of 41 informative sequences were established by split decomposition analysis and used as a basis to establish a substitution matrix and to score synonymous (s) and nonsynonymous (ns) substitutions. The number of observed in-phase stop codons within the nef sequences was comparable to that expected on a random basis. Similarly, the numbers of observed s and ns substitutions did not differ significantly from expected values. No codon position was preferentially mutated. The maximum sequence divergence increased in a linear manner, with approximately 4.4 nucleotide and approximately 3.2 amino acid changes per year. It appears that stochastic processes strongly influence short-term HIV nef quasispecies evolution in vivo.
