Secondary hemophagocytic lymphohistiocytosis due to Heartland virus.
Article in BMJ case reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
An older man from the mid-Southeastern USA presented with acute onset of fever, fatigue, and non-bloody diarrhoea. There was high suspicion for tick-borne illness given exposure history, clinical presentation and laboratory abnormalities. Despite prompt treatment with doxycycline, the patient clinically worsened. He was diagnosed with secondary hemophagocytic lymphohistiocytosis (HLH) due to Heartland virus (HRTV). This is the second documented case of secondary HLH due to HRTV, and the first in a relatively immunocompetent patient. Furthermore, though HRTV has been primarily concentrated in the Central USA, our case provides evidence of further geographic expansion of HRTV, mirroring the increased range of the Lone Star tick. Clinicians should consider HRTV when a patient with a clinical presentation consistent with tick-borne illness fails to respond to doxycycline. Furthermore, healthcare providers should be aware of the geographic expansion of HRTV and the potential of HRTV to lead to secondary HLH.
