False-positive dengue IgM test result in a patient with systemic lupus erythematosus: a case report.
Article in Asian biomedicine : research, reviews and news, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Dengue virus infection most commonly has mild-to-moderate nonspecific clinical presentations that overlap with other diseases. Dengue-specific tests are commonly used for those patients with acute febrile illness in dengue-endemic areas. There is one study in vitro that showed a false-positive dengue-immunoglobulin M (dengue IgM) test for blood from a patient with systemic lupus erythematosus (SLE). Here, we demonstrated a false-positive dengue IgM test in a patient with SLE. The patient had fever, cytopenia, and a skin rash, but her clinical variables more closely matched with the criteria for SLE than the dengue infection. Vasculitis-like-lesions supported prednisolone administration and her clinical symptoms improved. This case highlights that some patients with SLE can be misdiagnosed as having a viral infection. These two diseases have similar clinical findings, such as acute febrile illness, but they are different in terms of their treatments and disease prognosis.
