Characteristics of Pseudomonas aeruginosa keratitis at Ho Chi Minh eye hospital.
Article in International ophthalmology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
backgroundThe increasing drug resistance of Pseudomonas aeruginosa (PA) poses a serious challenge to the current treatment. Antibiograms of this pathogen often take 3-5 days, and treatment of Pseudomonas aeruginosa keratitis (PAK) is mainly based on preliminary physical examination, clinical experience, and medical guidelines. Pertinent clinical data on the causative agent and antibiotics for high efficacy are essential for early recognition and subsequent treatment. PURPOSE: To report the etiology, risk factors, treatment outcomes, antibiotic susceptibilities, and trends of PAK.
methodsThis retrospective study included culture-proven PAK cases at the Ho Chi Minh City Eye Hospital Cornea Department between January 2018 and December 2022. Culture results showing coinfection were excluded from the study.
resultsAmong 154 eyes infected by PA (n = 154) of 154 patients, ocular trauma was the leading risk factor (53.2%); only 16 patients had contact lenses (10.4%). Among the 154 eyes, 102/154 required surgical intervention (66.2%); and 31/154 eyes required evisceration (20.1%). PA was sensitive to tobramycin (95.9%), ciprofloxacin (91.9%), levofloxacin (91.9%), ofloxacin (87.4%), and moxifloxacin (20.0%). The prevalence of multidrug resistance (MDR) was 31.8%, and extensive drug resistance (XDR) was 3.9%. Poor outcomes (need for surgical intervention or final visual acuity ≤ CF 3 m) included age > 50 years, ocular surface diseases, deep infiltrate, large infiltrate size ≥ 5 mm, and ring infiltrate (p < 0.05).
conclusionPAK, which is associated with increasing drug resistance, poses significant challenges in terms of treatment, with 66.2% of patients requiring surgical intervention. With the rapid progression of PAK, early treatment with broad-spectrum and effective antibiotics is necessary. However, future research should focus on new methods to enhance treatment effectiveness.
