Short review/perspective: Critical early treatment of infections including meningitis and/or ventriculitis due to recurrent postoperative lumbar cerebrospinal fluid leaks, lumbar drains, or intracranial devices/implants.
Review in Surgical neurology international, 2025. 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: Early treatment of cerebrospinal fluid (CSF) infections, including meningitis and/or ventriculitis (MV) is critical to minimize morbidity/mortality. Infections/MV are typically attributed to; recurrent postoperative lumbar CSF fistulas with drainage through the skin (12.2-33.3%), lumbar drains, and/or various intracranial devices (i.e. external ventricular drains, intracranial pressure monitors). Methods: Lumbar MR examinations best document recurrent postoperative dural fistulas with subcutaneous extension leading to leaking wounds; the longer these leaks persist, the greater the risk of CSF infection and MV. Classical cranial MR findings of MV due to prior lumbar surgery, lumbar drains or multiple intracranial devices include; ventricular debris, ependymal enhancement, hydrocephalus, extra-axial fluid collections, infarcts (arteritis/ventriculitis), abscesses, and granulomas. Results: Surgery for recurrent postoperative lumbar CSF leaks typically warrant wound reexploration with direct sutured-dural repairs, use of muscle patch grafts (avoid fat - it resorbs), fibrin sealants/fibrin glues (FS/FG), lumbar drains, lumboperitoneal and/or pseudomeningocele-peritoneal shunts. For patients who additionally develop meningitis/ventriculitis, one should consider adding intraventricular (IVT) or lumbar intrathecal (IT) antibiotic therapy to routine intravenous antibiotics. Notably, all efforts should be made to avoid the high mortality rates associated with VM (i.e., 13% to 60%). Conclusion: Recurrent postoperative lumbar CSF leaks (i.e., especially after CSF breaches the skin), lumbar drains, and/or intracranial devices/implants may cause infections including meningitis and ventriculitis (MV). It is critical to recognize and treat these infections/MV early to avoid high morbidity and mortality rates.
