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.
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
backgroundCell-associated HIV-1 DNA, HIV-1 2-LTR circle, and HIV-1 unspliced RNA (usRNA) are important virological parameters for monitoring HIV-1 persistence and activation of latent HIV-1. Assays fully validated by CLIA and/or GCLP standards are needed for future clinical trials that seek to evaluate treatments directed towards HIV-1 cure.
objectivesTo determine performance characteristics of sensitive, moderate-throughput, digital droplet PCR (ddPCR) assays for cell-associated HIV-1 DNA, HIV-1 2-LTR circle, and HIV-1 usRNA that can detect a broad range of HIV-1 M-group subtypes. STUDY
designTo evaluate linearity, limit of detection, precision, and accuracy of each assay, contrived specimens were analyzed in a background of uninfected PBMC. Detection breadth was evaluated by in silico analysis of primer and probes sets and analysis of material harvested from PBMC infected in vitro with various HIV-1 subtypes. A cohort of clinical specimens from viremic and virologically suppressed individuals was analyzed to demonstrate applicability to clinical research.
resultsThe empirically determined limit of detection of these assays was 29, 7, and 60 copies per million PBMC for HIV-1 DNA, HIV-1 2-LTR circle, and HIV-1 usRNA, respectively. The assays detect a broad range of HIV-1 M-group subtypes. Finally, analysis of clinical specimens demonstrate that these assays can detect low levels of cell-associated HIV-1 DNA, HIV-1 usRNA, and HIV-1 2-LTR circle and correlate with clinical histories and viral loads of untreated and antiretroviral treated individuals.
conclusionsWe report the clinical validation of three HIV reservoir assays with broad HIV-1 coverage for future cure studies.
