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: This study aims to assess the anatomical positioning of critical nasal arteries in Chilean patients to improve the safety and efficacy of nonsurgical rhinoplasty procedures. Objectives: Using Doppler ultrasound, the study seeks to provide a precise vascular map that informs injection protocols and minimizes the risk of vascular complications, particularly in high-risk nasal regions. Methods: A cohort of 50 Chilean patients (ages 18-60, BMI 18.5-24.9 kg/m²) with no previous nasal procedures were evaluated. Doppler ultrasound was used to map the nasal vasculature, specifically targeting the dorsal nasal artery (DNA), radix, columella, and facial arteries in the piriform fossa. Key measurements included the depth of each artery relative to the periosteum and the skin surface. Descriptive statistics were used to calculate mean values and standard deviations for arterial distances, and comparative analyses were performed using the Student's Results: The anatomical mapping revealed significant variability in arterial positioning. The DNA was located within 1 mm of the periosteum in 10% of cases, presenting a high risk for vascular complications if not accurately mapped preinjection. The average depth of the facial artery in the piriform fossa was 4.65 ± 0.48 mm on the left side and 4.08 ± 0.53 mm on the right side, with statistically significant differences observed between sides ( Conclusions: This study provides critical insights into nasal vascular anatomy in a Latin American population, highlighting the clinical importance of Doppler ultrasound for preinjection mapping in nonsurgical rhinoplasty. By identifying high-risk areas and statistically significant anatomical variations, this research supports the need for a standardized, evidence-based protocol tailored to individual vascular profiles. The integration of Doppler ultrasound into clinical practice is recommended to enhance patient safety and optimize aesthetic outcomes, establishing a new standard for injectable procedures in high-risk nasal regions.
