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

Human immunodeficiency virus type 1 can generally use CCR3 and CCR5 for cell entry. We show that envelopes with novel phenotypes arise during "coreceptor switch": one loses the ability to use CCR3 (R5-only phenotype), and another gains use of CXCR4 in addition to CCR5 and CCR3 (R3/R5/X4-using phenotype). The envelope determinants for CCR3 use mapped to three amino acids. One, N356 in conserved region 3, is a potential glycosylation site and has not previously been associated with coreceptor use. The other two, R440 and N448 in conserved region 4, are proximal to but distinct from residues already identified as being important for CCR5 binding.
