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

We evaluated the FDA-approved Roche Cobas AmpliPrep/Cobas TaqMan (CAP/CTM) HIV-1 viral load assay for sensitivity, reproducibility, linearity, HIV-1 subtype detection, and correlation to the Roche Amplicor HIV-1 monitor test, version 1.5 (Amplicor). The limit of detection calculated by probit analysis was 23.8 copies/ml using the 2nd International WHO Standard and 30.8 copies/ml using Viral Quality Assurance (VQA) standard material. Serial dilutions of six patient samples were used to determine inter- and intra-assay reproducibility and linearity, which were very good (<8% coefficient of variation [CV]; between approximately 1.7 and 7.0 log(10) copies/ml). Subtype detection was evaluated in the CAP/CTM, Amplicor, and Bayer Versant HIV-1 bDNA 3.0 (Versant) assays using a commercially available panel. Versant averaged 0.829 log(10) copies/ml lower than CAP/CTM and Amplicor averaged 0.427 log(10) copies/ml lower than CAP/CTM for the subtype panel. Correlation with samples previously tested by Amplicor was excellent (R(2) = 0.884; average difference [Amplicor value minus CAP/CTM value], 0.008 log(10) copies/ml). Of the 305 HIV samples tested, 7 samples generated CAP/CTM titers between 1.0 and 2.75 log(10) copies/ml lower than those for Amplicor. Three of these samples revealed primer and probe mismatches that could account for the discrepancies. Otherwise, the CAP/CTM assay exhibits excellent sensitivity, dynamic range, reproducibility, and correlation with Amplicor in an automated format.
