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
Antimicrobial resistance is a major global health concern that requires innovative therapeutic strategies. This study aimed to address this challenge by designing Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-associated protein (CRISPR-Cas)-based plasmid systems for potential genome editing applications in multidrug-resistant (MDR) Klebsiella pneumoniae clinical isolates. Minimum inhibitory concentrations (MICs) of imipenem, meropenem, and ertapenem were determined according to European Committee on Antimicrobial Susceptibility Testing guidelines. All isolates (n = 5) were resistant, with MIC ranges of 4-128 μg/ml for imipenem, 8-64 μg/ml for meropenem, and 8-256 μg/ml for ertapenem. Resistance gene analysis revealed blaOXA-48-like and blaCTX-M-15 in all isolates, while blaNDM-1 was detected in one isolate. Two CRISPR-based plasmid systems, CRISPR-Cas9 and CRISPR-assisted cytidine deaminase, were designed. Target genes were amplified by polymerase chain reaction, and guide RNA (gRNA) sequences were designed from selected regions. Apramycin (50 μg/ml) was identified as a suitable selection marker. The pSGKP-AmpR(Pro)-ApmR plasmid was successfully constructed, whereas Cas9 and APOBEC constructs could not be cloned. Overall, this study highlights technical challenges in developing CRISPR-based tools for MDR K. pneumoniae and emphasizes the need for isolate-specific plasmid design and gRNA optimization.
