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

Foodborne outbreaks caused by parasites have long been a public health issue. Among the available contamination detection methods, qPCR is one of the most sensitive and specific. However, it can be cumbersome and error-prone, if used by unexperienced users. Moreover, qPCR reagents usually require freezer temperatures for transportation and storage. We present a gelified reaction format that allows the reagents to be stored at 2-8 °C for up to 90 days without losing performance. The gelification process eliminates most operator mistakes during reaction setup, and renders the qPCR plates ready-to-use. The new reaction makeup was evaluated using artificially contaminated samples of distinct food matrices for sensitivity, specificity, repeatability, reproducibility, and stability. Samples consisted of cilantro leaves and raspberry fruits spiked with
