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

Background: Kaposi sarcoma (KS) is a multifocal angioproliferative disorder linked to Human Herpesvirus-8 (HHV-8), presenting in four forms: classic, endemic, iatrogenic, and AIDS-related. AIDS-related KS remains prevalent among HIV-positive individuals despite widespread use of antiretroviral therapy. Gastrointestinal (GI) involvement is the most common extracutaneous manifestation, primarily affecting the upper GI tract. It is often asymptomatic and typically requires endoscopic evaluation. While commonly associated with advanced HIV, GI KS can occasionally precede an HIV diagnosis. Despite its strong link to HHV-8, disseminated KS may develop in HHV-8-negative patients with late HIV diagnoses, raising concerns about AIDS progression. Management primarily includes highly active antiretroviral therapy (HAART), while liposomal doxorubicin is reserved for extensive disease to ensure symptom control, lesion regression, and improved survival. Case Presentation: This case report describes a rare presentation of disseminated GI KS in an HHV-8-negative patient newly diagnosed with HIV, indicating potential AIDS progression. The patient exhibited violaceous cutaneous lesions and GI symptoms, including abdominal pain and dysphagia. Endoscopy revealed esophageal masses and ulcer-like lesions in the stomach and duodenum, with histology and IHC confirming KS despite negative HHV-8 status. Management included HAART and liposomal doxorubicin, with close IRIS monitoring. The patient remained hemodynamically stable and was discharged on HAART, chemotherapy, and prophylactic antifungal and antibiotic therapies following negative cultures and stable clinical status. Conclusion: This case highlights the need for vigilance in the atypical manifestation of HHV-8-negative disseminated GI KS in an undiagnosed HIV-positive patient, emphasizing the clinical presentation, diagnostic approach, and disease management. The patient's stabilization underscores the importance of early recognition, comprehensive diagnostic evaluation, and a multidisciplinary approach in managing complex cases.
