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

There is a clear need for an instrument-free molecular diagnostic system for detecting human immunodeficiency virus type 1 (HIV-1) RNA or DNA that can be used in developing countries. Such a test could be used for early diagnosis of HIV-1 infection during infancy and could serve as a surrogate end point for vaccine trials. We developed the IsoAmp HIV-1 assay (BioHelix Corporation), which targets the HIV-1 gag gene with use of isothermal reverse-transcription helicase-dependent amplification chemistry. The IsoAmp HIV assay uses a disposable amplicon containment device with an embedded vertical-flow DNA detection strip to detect the presence of HIV-1 amplicons. The vertical-flow DNA detection strip has a control line to validate the performance of the device and a test line to detect the analyte. The analyte is detected by a sandwich immunoassay for reporter moieties on a capture probe and a detection probe. The control line consists of the detection probe reporter moiety conjugated to the vertical-flow DNA detection strip. The preliminary limit of detection of the IsoAmp HIV assay was evaluated by testing serial dilutions of HIV-1 armored RNA (Assuragen). We found that 21 (75%) of 28 assays yielded positive results when 50 copies of HIV-1 armored RNA were input into the IsoAmp HIV reaction.
