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

Plasma HIV-1 RNA was measured in 306 samples, collected from 273 highly active antiretroviral therapy-experienced men, using both the Roche COBAS TaqMan (limit of detection = 20 copies per milliliter) and Roche Amplicor (limit of detection = 50 copies per milliliter) assays. Mixtures of Gaussian distributions incorporating left-censored data were used in analyses. The more sensitive TaqMan assay estimated that 23% and 0.0003% of HIV-1 RNA values would be below 1 copy per milliliter and 1 copy per 3 L, respectively. This is in sharp contrast to the overestimation provided by the less sensitive Amplicor assay, whereby the corresponding predicted percentages were 51% and 1%. Both assays appropriately characterized suboptimal virologic response as the rightmost peaks of both distributions provided an excellent fit to the observed data. Our results based on a widely available 20 copies per milliliter sensitive assay reproduce those obtained using customized assays that quantified HIV-1 RNA values as low as 1 copy per milliliter.
