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

The plaque-forming assay is the gold-standard method for measuring infectious viral particles. In this technique, lytic viruses infect and destroy host cells, but their spread is restricted by a viscous overlay medium. As a result, new viral particles can only infect neighboring cells, leading to localized clear areas known as plaques, which become visible after staining the remaining living cells. The number of plaques reflects the number of infectious viral particles initially present in the sample and is reported as plaque-forming units (PFU) per sample volume. In this protocol, we describe step by step how to perform a plaque-forming assay to determine the concentration of chikungunya virus in a cell culture supernatant.
