Detecting Monkeypox Virus by Immunohistochemistry.
Article in Journal of cutaneous pathology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundMpox (formerly known as monkeypox), a zoonotic disease caused by Monkeypox virus (MPXV), has become an international outbreak since May 2022. Mpox often presents with a mild systemic illness and a characteristic vesiculopustular skin eruption. In addition to molecular testing, histopathology of cutaneous lesions usually shows distinctive findings, such as epidermal necrosis, balloon degeneration, papillary dermal edema, and focal dermal necrosis, which have proven helpful in the diagnosis of mpox. Viral cytopathic changes with areas of multinucleation, smudging of the nuclei, and intracytoplasmic inclusions have also been described. Although useful, these features are relatively nonspecific. The use of a monoclonal antibody for immunohistochemical (IHC) staining of MPXV may be a useful tool in confirming mpox infection.
methodsThree cases of PCR-confirmed mpox were biopsied and subjected to IHC staining with a monoclonal MPXV-specific antibody targeting viral envelope protein A29. As controls, cell lines transduced to express other MPXV viral antigens and samples of cutaneous viral infections involving Molluscum contagiosum, Herpes simplex, Herpes zoster, or Cytomegalovirus were also subjected to IHC staining with this antibody.
resultsAll three mpox patient biopsies performed on lesional skin subjected to MPXV IHC staining reliably detected viral infection in lesional skin with a diffuse cytoplasmic and focally nuclear staining pattern. No staining was seen in transduced cell lines expressing off-target MPXV viral antigens and in lesional skin of other common viral infections listed above.
conclusionsThe monoclonal MPXV-specific antibody may be used as an adjunct tool to confirm mpox infection.
