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

Cryptococcus neoformans is an opportunistic fungal pathogen primarily targeting immunosuppressed populations in both resource-rich and resource-limited nations. Successful treatment is limited to a few antifungals that have become compromised by cryptococcal resistance, leading to intensive research seeking new drug candidates. Two distinguishing hallmarks of this species are the ability to develop a polysaccharide capsule and melanization of the fungal cells. These also act as virulence factors, protecting this pathogen in the host as well as in the environment. Here we describe two classic methods to document capsule and melanin. Although initially described and documented several decades ago, these methods remain relevant in spite of the advent of more sophisticated methodology, due in part to their simplicity and cost efficiency. © 2021 Wiley Periodicals LLC.
