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
Clinical vampirism, or Renfield syndrome, is a rare psychiatric phenomenon characterized by the compulsion or desire to consume blood and has been described in association with psychotic and other psychiatric disorders. Reported presentations may include blood-drinking behaviors, urges to consume blood, and delusions or hallucinations involving blood. This report details the case of a 28-year-old man with a history of treatment-resistant schizoaffective disorder and adolescent-onset polysubstance use who presented with prominent vampiric delusions. The patient endorsed urges to consume blood in the setting of persistent auditory hallucinations and religious delusions without acting upon these impulses. His presentation was complicated by psychosocial vulnerabilities, including chronic homelessness, medication nonadherence, and prior incarceration. Following psychiatric evaluation and resumption of antipsychotic therapy, his homicidal ideation decreased, and he was transferred to an inpatient psychiatric facility for continued treatment. This case highlights the relationship between clinical vampirism and underlying psychotic disorders and underscores the importance of addressing barriers to continuity of care when managing these rare presentations.
