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

Background: Various terms are used to categorize the extent of antibiotic resistance in bacteria. It is important to standardize the classification of drug-resistant bacteria to ensure clarity and generalizability of evidence across different disciplines and inform policy. Methods: A literature search for articles published between 2011 and August 2025 indexed in MEDLINE and EMBASE, which used the terms: multidrug resistance, extensively drug resistance, pan-drug resistance, difficult-to-treat or usual drug resistance in either the methods or results sections, and which reported bacterial pathogens relevant to human health was performed. Data extracted were analysed quantitatively using multivariable logistic regressions and qualitatively to examine the study characteristics that adopted various definitions. Results: From 2465 eligible records, the most commonly used definition was by Magiorakos Conclusion: The progressive development of antibiotic resistance necessitates updated definitions to include newer antibiotic agents and genotypes. These revised definitions can also prioritize antibiotic classes according to their efficacy profile, toxicity and availability, and should be validated against clinical datasets to correlate with patient outcomes.
