Temporal lobe brain abscess: Etiology, microbiology, surgical management, and outcomes - A systematic review.
Review in Surgical neurology international, 2026. 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
Background: Temporal lobe brain abscess is an uncommon but clinically significant intracranial infection most frequently associated with otogenic disease. Although brain abscess has been widely studied, location-specific analyses focusing on the temporal lobe remain limited. This systematic review aimed to evaluate the etiology, microbiology, surgical management, and outcomes of temporal lobe brain abscess reported in the literature. Methods: A systematic literature search was performed in PubMed, Scopus, Web of Science, and Google Scholar to identify studies reporting temporal lobe brain abscess. Eligible studies included case reports and case series with extractable clinical data. Data were extracted regarding demographics, predisposing factors, microbiological findings, abscess characteristics, treatment strategies, and clinical outcomes. Risk of bias was assessed using Risk of Bias in Non-randomized Studies of Interventions for case series and the Joanna Briggs Institute checklist for case reports. Descriptive analysis was performed for the overall cohort, and pooled estimates were calculated for variables with sufficient data. Results: Forty studies, including 105 patients, were reviewed, but incomplete reporting limited the pooled analysis to 60 patients. Men comprised 64.76% (35/60), with a pooled proportion of 0.588 (95% confidence interval [CI]: 0.474-0.702; I Conclusion: Temporal lobe brain abscess most commonly arises from otogenic infection and demonstrates a heterogeneous microbiological profile. Minimally invasive aspiration techniques represent the predominant surgical strategy, while open surgical approaches are reserved for complex cases. Early diagnosis, appropriate antimicrobial therapy, and timely surgical management remain essential for optimizing patient outcomes.
