Tandem Bioluminescent Tests for Rapid Detection of Urinary Tract Infections and Antimicrobial Resistance Using a Portable Luminometer.
Article in Analytical chemistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
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
Urinary tract infections (UTIs) are among the most common bacterial infections in the world. Additionally, increasing antimicrobial resistance (AMR) further complicates the task of effective therapy for UTIs and, thus, presents a serious public health hazard. The standard diagnosis for UTI and AMR requires access to laboratory infrastructures, well-trained personnel, and long periods of processing time, all of which are factors increasing healthcare costs and inappropriate antibiotic treatment. Here, we designed bioluminescence-based tests for UTI and AMR detection that can be performed in tandem using a portable luminometer in ∼30 min. To date, no methods have been reported that can simultaneously detect both UTI and AMR using the same detection principle and portable device as described here, offering a significant advantage in streamlining testing. Our UTI test is based on whole-cell bioluminescence assay, and AMR detection employs a modified ATP-based bioluminescence detection. Our test can detect UTI in 5 min at a bacterial level as low as 20,000 CFU/mL, which meets the clinically significant threshold of 100,000 CFU/mL. Antibiotic resistance was monitored using a modified ATP-based bioluminescence test within 30 min. The test showed no interference from potential urinary components, such as glucose, urea, commensal flora, or pH variations. A clinical sample (
