Optimizing transducer choice for the detection of alveolar-interstitial syndrome in dogs and cats: an evidence-based review.
Review in Frontiers in veterinary science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Alveolar-interstitial syndrome (AIS) is a common ultrasonographic finding in dogs and cats with pulmonary pathology, including cardiogenic pulmonary edema, noncardiogenic pulmonary edema, pneumonia, acute respiratory distress syndrome, and pulmonary contusion. Point-of-care lung ultrasound (LUS) has emerged as a rapid, noninvasive, and repeatable diagnostic tool for identifying AIS in emergency and critical care patients. Despite its increasing clinical adoption, transducer selection remains largely operator-dependent, with limited evidence-based guidance for veterinary applications. This review synthesizes current veterinary and human literature to evaluate how transducer type influences the detection and characterization of AIS in small animals. The acoustic properties, field of view, penetration depth, and resolution trade-offs of linear, curvilinear, and microconvex transducers are discussed in relation to B-line visualization, pleural line assessment, and detection of subpleural consolidations. Comparative performance data, including the results of recent veterinary studies, are integrated to highlight differences in diagnostic sensitivity, specificity, and interobserver reliability. A clinical decision-making framework is proposed, outlining optimal transducer selection by patient size, suspected pathology, and clinical context (triage, monitoring, follow-up). Practical considerations such as transducer availability, equipment ergonomics, and operator training are addressed. Knowledge gaps and future research priorities, including the role of portable devices and AI-assisted image interpretation, are identified. By consolidating the available evidence, this review aims to standardize and optimize transducer selection in veterinary lung ultrasound, improving diagnostic accuracy, accelerating clinical decision-making, and ultimately enhancing patient outcomes in small animal emergency and critical care.
