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

A technique to assess the ability of distinct Candida strains to efflux substrates, as well as to compare the effectiveness of efflux inhibitors, is important for analysis of antifungal drug resistance mechanisms and the mode of action of antifungals. We describe a method that measures the ability of Candida species to extrude the fluorescent dye Nile red as an output for efflux activity. This involves exposing cells to Nile red and using flow cytometry to quantify cellular fluorescence, enabling numerous samples to be processed in a limited time frame. This protocol provides a simple, yet effective method for quantifying efflux in drug-resistant Candida species. © 2020 Wiley Periodicals LLC Basic Protocol 1: Growth and sample preparation of stained Candida Basic Protocol 2: Quantitative measurement of fluorescence by flow cytometry Alternate Protocol: Qualitative determination of fluorescence using microscopy.
