Ecological overview of hard ticks (Ixodida: Ixodidae) in Nagasaki prefecture of western Japan during winter 2021-2022.

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
In Japan, Japanese spotted fever, Lyme disease and severe fever with thrombocytopenia syndrome caused by Ixodidae species are endemic. To prevent and control the diseases, fundamental understandings in tick ecology are crucial. Hence, this study aimed to analyse tick species richness and abundance across Nagasaki prefecture including its remote islands from a wide range of environments. A total of 74 sampling points screening during winter 2021-2022, using dragging method resulted in 14,883 tick samples (279 adults, 7148 nymphs and 7456 larvae) in 11 species belonging to four genera. Haemaphysalis flava dominated adult populations, while H. formosensis was predominant among nymphs. Both species are possible vectors of Japanese spotted fever and severe fever with thrombocytopenia syndrome. The ecological analysis revealed more complex species distribution in the remote islands compering to the main island in both adults and nymphs. In addition, the ground temperature was a significant regulatory factor for both adults and nymphs. The research provides valuable insights on tick distributions, ecological groupings and environmental preferences in Nagasaki. These findings contribute to the fundamental understanding of tick ecology and could contribute to design strategies for tick population control and tick-borne disease prevention in Nagasaki or possibility to nearby areas.
