Optimization of pathogen detection in abscess specimens: a 6-year retrospective study.
Observational study in European journal of medical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThis study aimed to evaluate the impact of optimized diagnostic protocols on pathogen detection rates in abscess specimens.
methodsOur retrospective study analyzed 1,297 abscess specimens collected between 2018 and 2024 using an enhanced diagnostic protocol combining four key methodologies: routine aerobic/anaerobic culture, gram-stain microscopy, acid-fast bacilli staining, and blood culture bottle enrichment techniques.
resultsThe implementation of optimized diagnostic protocols significantly enhanced pathogen detection efficacy (P < 0.001, χ = 9.663), achieving an overall positivity rate of 81.9% (1,062/1,297)-a 20.1 percentage point improvement over conventional methods. Among culture-positive specimens, polymicrobial infections were identified in 27.6% of cases (293/1,062). A total of 1,651 microbial isolates were recovered, dominated by gram-negative bacteria (50.6%, 836/1,651) with Escherichia coli (55.0%), Klebsiella pneumoniae (23.0%), and Acinetobacter baumannii (4.0%) as predominant species. Gram-positive cocci accounted for 33.7% (557/1,651), primarily Streptococcus spp. (45.0%), Staphylococcus aureus (19.0%), and Enterococcus faecium (6.0%). Enhanced methodology detected 261 additional pathogens (20.1% of total yield), including anaerobes (33.7%), smear-positive organisms (32.2%), acid-fast bacilli (6.9%), and Brucella melitensis (1.5%). Anatomic distribution analysis revealed perianal abscesses (358 cases, 407 isolates) predominantly associated with E. coli (51.8%), K. pneumoniae (14.7%), and Streptococcus spp. (15.7%), followed by maxillofacial infections (244 cases, 297 isolates; 18.0%). Other significant sites included abdominal abscesses/peritonitis (17.0%), hepatic abscesses (5.2%), and Periappendicular abscess (5.5%).
conclusionsSystematic optimization of diagnostic protocols significantly enhanced pathogen detection in abscess specimens, demonstrating substantial clinical utility for infectious disease management. These findings support the adoption of comprehensive, standardized approaches for abscess specimen processing.
