Neuroimaging for prognosis of central nervous system infections: a systematic review and meta-analysis.
Article in Annals of intensive care, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundCentral nervous system (CNS) infections carry a severe prognosis and often require intensive care unit (ICU) admission. This study evaluated the prognostic value of neuroimaging in patients with all-type CNS infections.
methodsUsing a predefined strategy, we first conducted a systematic search of PubMed/MEDLINE, PubMed Central, Embase, Cochrane and Google Scholar. Eligible studies published between January 1st, 2000, and June 1st, 2023, were included. We considered randomized controlled trials, non-randomized trials, cohort studies, excluding abstracts, cost-effectiveness analyses, letters, conference proceedings, systematic reviews, and meta-analyses. Two authors independently screened publications and extracted data. The meta-analysis was performed using a random-effects model. The main outcomes were (1) unfavorable outcome, defined as severe functional disability or death, and (2) mortality. Pooled odds ratios (OR) and 95% confidence intervals (95%CI) were calculated for each neuroimaging feature. We performed prespecified subgroup analyses depending on type of CNS infection (bacterial meningitis, CNS tuberculosis, CNS cryptococcosis, viral encephalitis, and brain abscess), country income, and ICU admission status.
resultsOf 7,864 studies identified, 83 met the inclusion criteria, with 48 studies (6,434 patients) included in the meta-analysis. Abnormal MRI (OR: 3.55; 95%CI: 1.81-6.96; I²=0%), brain ischemia (OR: 4.65; 95%CI: 3.14-6.88; I²=28.5%), and hydrocephalus (OR: 4.56; 95%CI: 2.49-8.36; I²=61.5%) were significantly associated with unfavorable outcome. Hydrocephalus (OR, 3.99; 95%CI 1.83-8.70; I²=61%) and brain ischemia (OR, 3.51; 95%CI, 2.22-5.54; I²=16.4%) were associated with mortality. These associations remained consistent in patients with bacterial meningitis and in patients with CNS tuberculosis, but not in other CNS infections. Subgroup analyses depending on country income and ICU admission status revealed similar findings.
conclusionNeuroimaging provides essential prognostic information in patients with CNS infections. Abnormal MRI findings, cerebral ischemia, and hydrocephalus are associated with unfavorable outcome, particularly in bacterial meningitis and CNS tuberculosis. These neuroimaging features should be considered when discussing prognosis in affected patients.
