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

Sensitive, specific and rapid molecular diagnosis of respiratory diseases in animals and humans is critical to facilitate appropriate control measures and treatment. Conventional polymerase chain reaction (PCR)-based molecular diagnostics requires relatively expensive equipment and trained staff, restricting its use to centralized laboratories with significant delays between sample collection and test results. Herein, we report a highly sensitive, rapid, point-of-need, two-stage-molecular test that requires minimal instrumentation and training. Our test, dubbed Penn-RAMP, combines recombinase polymerase amplification (RPA, 38 °C) and loop-mediated isothermal amplification (LAMP, 63 °C) in one tube, enabling nested, two-stage isothermal amplification. We demonstrate Penn-RAMP's efficacy by testing for two common viral respiratory diseases of chickens: infectious laryngotracheitis (ILT) and infectious bronchitis (IB) that impose great economic burden worldwide. Test results of clinical samples with our closed-tube Penn-RAMP assays concord with the gold standard quantitative PCR (qPCR) assay; with 10-fold better limit of detection than LAMP and qPCR. Our closed-tube Penn-RAMP assays have the potential to greatly reduce false negatives while requiring minimal instrumentation and training.
