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

backgroundPoint of need diagnostics provide efficient testing capability for remote or austere locations, decreasing the time to answer by minimizing travel or sample transport requirements. Loop-mediated isothermal amplification (LAMP) is an appealing technology for point-of-need diagnostics due to its rapid analysis time and minimal instrumentation requirements.

methodsHere, we designed and optimized nine LAMP assays that are sensitive and specific to targeted bacterial select agents including Bacillus anthracis, Francisella tularensis, Yersinia pestis, and Brucella spp. Evaluation of each assay determined preliminary limit of detection (LOD) with LOD confirmed across 60 replicates (≥ 95% positivity rate). Testing across a robust set of strains of the target agent, common DNA agents, and near-neighbors documented sensitivity and specificity for independent assays.

resultsSpecifically, all assays were 100% specific and sensitive except for Y. pestis Caf1 (90% inclusive across Y. pestis strains).

conclusionHere, we optimized assay turn-around-time, decreasing a standard 60 min traditional polymerase chain reaction (PCR) to 30 min using LAMP with positive results in as little as 5-10 min. Incorporating point of need sample processing and evaluating the potential inhibitory impact of sample matrices such as whole blood and soil would be needed to enable this test system for use on field-forward clinical and environmental sample testing.
