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
backgroundFleas are the most common ectoparasites of dogs and cats worldwide, causing dermatological problems and transmitting pathogens, some of zoonotic concern.
objectiveTo assess the knowledge and practices (KP) of companion animal owners in Mainland Portugal regarding fleas, flea-borne pathogens, and measures for their treatment and prevention.
methodsA cross-sectional study conducted between March 2022 and March 2023 targeted dog and/or cat owners from the five Mainland Portuguese NUTS2 (Nomenclature of Territorial Units for Statistics) regions. Participants answered a self-administered sociodemographic and KP questionnaire. Individual KP scores were calculated based on predefined grades.
resultsThe study included 550 participants: 212 exclusively dog owners, 158 exclusively cat owners, and 180 owners of both species. The median age was 40 years, and 69.9% were female. Veterinarians were the primary source of information about fleas and flea-borne pathogens. Over 10% of participants were unable to identify adult fleas' characteristics. Most participants (90.3%) identified the environment outdoors as the most common source of infestation, while 54.4% mentioned contact with other animals. While 81.9% recognised that fleas transmit pathogens, only 12.7% could name specific pathogens; the flea bite was the most identified route of transmission. Most participants (87.6%) were aware that fleas parasitising pets could also parasitise humans. The most common flea treatment schedule was every 3-4 months, primarily to prevent infestation, while cleaning and vacuuming house/animal resting places were the preferred control measures. Multivariate analysis revealed that younger participants (≤ 50 years, for fleas), females (for flea-borne pathogens), those with higher education, and residents in the NUTS2 Centro, Área Metropolitana de Lisboa (AML), or Algarve regions had above-median knowledge scores. Higher education, residence in NUTS2 Centro or AML, pet ownership of only cats or dogs, and higher knowledge scores were associated with improved practices.
conclusionsMost pet owners were aware that fleas transmit pathogens and knew ways to prevent infestations. However, knowledge gaps remain in understanding flea biology and the specific routes of transmission of flea-borne pathogens, which may hinder effective prevention efforts. Veterinarians play a crucial role in educating owners about flea management and prevention of flea-borne infections, aiming at reducing transmission risks to both animals and humans.
