1 · What the graph read from it

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.

2 · The registry

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

Introduction: The increasing incidental discovery of asymptomatic cerebral cavernous malformations (CCMs) in military pilots poses a significant challenge for aeromedical certification, due to the potential risks of epilepsy and symptomatic hemorrhage. There is a lack of evidence-based guidelines for the fitness-to-fly assessment of military pilots with such lesions. Methods: A retrospective study was conducted on military pilots diagnosed with asymptomatic CCMs at our center. Demographic, flight-related, and lesion data were collected. A multi-disciplinary review board evaluated in-flight incapacitation risk by assessing epilepsy and hemorrhage potential based on established clinical risk factors. Results: Among 22 military pilots harboring 23 CCMs, 11 were permanently disqualified from flight duties due to a high assessed risk of in-flight incapacitation. This included five pilots disqualified for cortical lesions posing a significant epilepsy risk, and six pilots disqualified due to a high risk of symptomatic hemorrhage associated with brainstem location, eloquent area involvement, or Zabramski Type II lesions. The remaining 11 pilots, with solitary Zabramski Type III or IV lesions that were neither cortical nor located in eloquent areas, were approved for unrestricted flying status. During a mean follow-up of 34 months, these pilots demonstrated stable lesion morphology on imaging and experienced no neurological events. Conclusion: A risk-stratified aeromedical certification protocol for asymptomatic CCMs in military pilots appears viable. Strict disqualification for high-risk lesions combined with conditional clearance for low-risk lesions, supported by rigorous annual monitoring, can balance flight safety with career preservation. This preliminary framework requires further validation.
