Clinical impact of antibiotic resistance in odontogenic infections: a 12-year analysis of 740 cases.

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
objectivesThis study aimed to investigate the microbial spectrum and resistance patterns in surgically treated odontogenic infections and to assess the clinical impact of resistance, including systemic complications and hospitalization. Resistance rates were additionally evaluated in relation to reported penicillin hypersensitivity.
methodsA total of 740 inpatient cases with microbiological testing from surgically treated odontogenic infections at the Jena University Hospital from January 1, 2012, to December 31, 2023, were analyzed. Resistance rates were assessed at infection level. Time trends were analyzed using Poisson regression. Associations between resistance rates and clinical variables were evaluated using binary logistic regression.
resultsClindamycin resistance was observed in 38.9% of infections, while amoxicillin/clavulanate (6.9%) and moxifloxacin (4.5%) showed lower resistance rates. No statistically significant trends in resistance rates were observed. Moxifloxacin resistance increased the risk of systemic complications (OR: 10.875; 95%-CI: 2.364-50.017; p = 0.002), while no significant associations were found between antibiotic resistance and prolonged hospitalization. A history of penicillin hypersensitivity was associated with increased clindamycin resistance (OR: 2.156; 95%-CI: 1.038-4.480; p = 0.04).
conclusionsClindamycin exhibits high resistance rates in odontogenic infections and should be critically re-evaluated as empirical therapy, especially in patients with penicillin hypersensitivity. Given the overall low resistance rates to moxifloxacin, resistance to this agent indicated highly resistant infections and was associated with an increased risk of systemic complications. CLINICAL RELEVANCE: Continuous resistance surveillance and adaptation of empirical therapy are essential for managing severe odontogenic infections and reducing life-threatening infection-related complications, emphasizing the need for antimicrobial stewardship.
