Diagnostic challenges in dengue encephalitis: subtle imaging findings and initially negative laboratory test in a kidney transplant recipient.
Article in Arquivos de neuro-psiquiatria, 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
Dengue encephalitis is an uncommon neurological complication of dengue virus infection. In immunocompromised patients, such as solid organ transplant recipients, the clinical presentation may be atypical and nonspecific, posing significant diagnostic and therapeutic challenges. We report a clinical case and use it as a framework to discuss key considerations for suspicion of dengue encephalitis. Topics include optimal timing for clinical suspicion, essential differential diagnoses, and the most appropriate diagnostic strategies. Emphasis is placed on the correct interpretation of cerebrospinal fluid findings and recognition of subtle brain magnetic resonance imaging changes that may support the diagnosis. The discussion also reviews current evidence on dengue encephalitis in immunocompromised populations, highlighting implications for timely diagnosis and management in this vulnerable group.
