Knowledge, risk perceptions and practices regarding mosquito-borne arboviral diseases among physicians in Baden-Wuerttemberg, Germany: A cross-sectional questionnaire-based analysis.

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
Background: Mosquito-borne arboviral infections (MBAI), including dengue and chikungunya viruses transmitted primarily by Methods: We developed a 44-item questionnaire to assess KPP related to arboviral infections. We conducted a cross-sectional survey between May to October 2024 using Results: A total of 473 physicians participated in the survey (response rate of ∼6%); 55.8% were women and 60% were aged 40-59 years. The median normalized scores were knowledge 68.6 (IQR 55.4-79.7), perception 33.3 (26.7-46.7), and practices 54.6 (37-68.5). A majority of respondents, 75.8% (N = 354) reported only partial knowledge on arboviral transmission routes. 68.9 % (N = 324) desired more information on endemic regions for arboviruses. In a clinical vignette (fever with truncal exanthema after travel to southern France), 42% would order arboviral testing, compared to 90% for a pregnant traveler returning from Brazil. Over 73% (N = 341 of 462) physicians reported a no to low risk of autochthonous West Nile virus (WNV) infections, and only travel-associated indication was widely recognized (89.4% (N = 373). Knowledge and perception scores were positively associated with practices (OR: 1.16 [95% CI 1.11-1.21] and 1.14 [1.09-1.20], both p < 0.0001). Conclusions: This first survey of physician KPPs on MBAI in Germany highlights substantial knowledge gaps, misaligned risk perceptions, and travel-centric diagnostic mindset, where the risk of infections locally and within Europe was underrecognized. Despite a low response rate, this study provides a valuable reference point for preparedness planning. Integrating arbovirus-related content into continuing medical education, supported by public health information campaigns and surveillance feedback, are likely to contribute to strengthening clinical awareness and may support improved diagnostic and counselling practices in the face of expanding vector presence and increasing risk of autochthonous infections.
