Article in Infectious diseases and therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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.
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
introductionStenotrophomonas maltophilia is an opportunistic pathogen associated with various nosocomial infections and is known for its intrinsic multidrug resistance. This study aims to provide a comprehensive overview of the epidemiology and resistance patterns of S. maltophilia in China from 2014 to 2021.
methodsData were extracted from the China Antimicrobial Resistance Surveillance System (CARSS) and the Blood Bacterial Resistance Investigation Collaborative System (BRICS), encompassing 1412 medical institutions across 31 provinces in China. We analyzed the prevalence of S. maltophilia in clinical isolates, focusing on specific patient populations and departments, as well as resistance profiles to recommended first-line antibiotics, including sulfamethoxazole-trimethoprim, levofloxacin, and minocycline.
resultsA total of 514,768 S. maltophilia strains were analyzed. The overall prevalence of S. maltophilia among all clinical bacterial isolates remained stable at approximately 2.1%, with higher rates observed in intensive care units and elderly patients. Resistance rates to sulfamethoxazole-trimethoprim decreased from 9.8% in 2014 to 7.5% in 2021. In contrast, resistance to levofloxacin showed a slight upward trend, increasing from 8.5% in 2014 to 9.5% in 2021. Meanwhile, minocycline resistance remained low, fluctuating marginally from 2.7% in 2014 to 1.7% in 2021.
conclusionsThis study highlights the stable prevalence of S. maltophilia in clinical settings in China and the overall low resistance rates to recommended first-line antibiotics. However, alarmingly high resistance rates were observed in specific specimen types, particularly in blood cultures, suggesting that minocycline may be the only reliable therapeutic option among the six tested antibiotics for treating such infections in China. Continuous surveillance and effective infection control measures are essential to manage S. maltophilia infections, particularly in vulnerable populations. Future research should focus on measuring the true burden of these infections and monitoring the susceptibility of the newly introduced antibiotics, such as cefiderocol.
