Hepatitis B Virus Reactivation Following Treatment of HNSCC With Cisplatin.
Article in Journal of investigative medicine high impact case reports. 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
Hepatitis B Virus (HBV) reactivation is a known complication of intense immunosuppression with B-cell depleting monoclonal antibody therapy and transplantation immunosuppression. HBV reactivation has occurred following treatment with chemotherapy regimens for hematologic malignancies and solid tumors. There are 2 prior case reports of HBV reactivation following cisplatin monotherapy for head and neck squamous cell carcinoma (HNSCC). Here, we present a case of a 49-year-old Caucasian male with a past medical history of laryngeal squamous cell carcinoma (SCC). There are no consensus guidelines on how to define hepatitis B reactivation. There are guidelines on when to initiate prophylaxis with Entecavir while on immunosuppressive therapy with risk according to medication category and hepatitis B surface antigen/hepatitis B core antibody IgG serology. CDC recommends screening everyone. American Society of Clinical Oncology (ASCO) now with a recent update in 2020 recommends screening everyone. There is a definite role of immunosuppression in HBV reactivation, however, there is also direct enhancement by cisplatin of viral replication by creating endoplasmic reticulum stress which increases HBV DNA indirectly. Finally, cytotoxicity enhances HBV reactivation and immune reconstitution post withdrawing immunosuppressive treatment. Because of the effects of chemotherapy, aka cisplatin goes beyond immunosuppression-related reactivation of HBV, our recommendations are in line with CDC and ASCO to screen all patients for HBV before onset of chemotherapy and start Entecavir/Tenofovir Disoproxil Fumarate before the onset of chemotherapy for HBV-positive patients.
