County-level surveillance for the American dog tick (Dermacentor variabilis) and Rickettsia species in Kentucky.
Article in Scientific reports, 2026. 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
Spotted fever group (SFG) rickettsiosis includes a group of illnesses with similar symptoms caused by Rickettsia species bacteria. While Rickettsia rickettsii, the agent of Rocky Mountain spotted fever (RMSF) is a well-known pathogen, other SFG Rickettsia spp. can infect ticks and occasionally contribute to human disease. We conducted county-level surveillance of Dermacentor variabilis ticks in Kentucky to characterize the distribution and diversity of SFG Rickettsia. Ticks were collected from the environment from 2019 to 2024 by dragging a white cloth and through our Kentucky Tick Submission Program. In total, 2,023 D. variabilis ticks were collected from 114 counties. Rickettsia species were detected in 1% of Dermacentor variabilis ticks, including R. montanensis (0.47%), R. amblyommatis (0.13%), and R. parkeri (0.13%). These findings indicate that, while SFG Rickettsia are present at low levels in D. variabilis ticks in Kentucky, continued surveillance in counties with reported SFG rickettsiosis cases is essential to improve clinical recognition and guide public health efforts to monitor and prevent SFG rickettsiosis.
