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
Understanding how vector population structure influences pathogen circulation remains a major challenge in tick-borne disease ecology, particularly in biogeographically transitional regions. Dermacentor reticulatus, a widespread Palearctic tick species and vector of multiple pathogens, provides a useful system to investigate this relationship in a biogeographically complex landscape. Here, we combined mitochondrial (cox1) and nuclear (ITS2) population genetic analyses with broad-spectrum pathogen screening in host-seeking D. reticulatus from Anatolia, a major ecogeographical transition zone of the eastern Palearctic. Population genetic analyses revealed moderate haplotype diversity, low nucleotide divergence, and limited regional structuring, with Anatolian populations clustering within widespread eastern Palearctic lineages. Global haplotype networks indicated extensive haplotype sharing with Eurasian populations, consistent with historical connectivity and possible host-mediated dispersal. In contrast to the relatively limited genetic structuring observed in tick populations, pathogen detections showed marked spatial heterogeneity. Rickettsia raoultii was detected predominantly in northeastern populations, whereas Coxiella burnetii detections were concentrated within a single locality. Other detected agents, including piroplasmids and Anaplasma phagocytophilum, occurred sporadically and showed no clear spatial pattern. Together, these findings suggest a mismatch between vector genetic structure and pathogen spatial distribution. Comparisons with sympatric Dermacentor marginatus populations further suggested species-specific differences in population structure and pathogen assemblages. The observed spatial heterogeneity in pathogen detections may reflect differences in local ecological conditions, host communities, and transmission dynamics. These findings provide new insight into the eco-epidemiological dynamics of D. reticulatus-associated pathogens in Anatolia and contribute to improved understanding of tick-borne pathogen (TBP) circulation at the southeastern margin of the Palearctic region.
